As if signing up for the Fantasy Alarm Assistant GM wasn't a good enough decision already, we present to you even more assistance in setting your lineups this week.

Every Friday throughout the NFL regular season I will be sending you this lineup helper that I like to call: Tough Decisions. In this article I will break down players with similar value, ranking and projection heading into this coming week.

Let's take a look at the TOUGH DECISIONS for Week 8:

Quarterbacks

Andrew Luck (@Panthers) or Drew Brees (vs. Giants)

The Case for Luck: Luck has a ton of weapons and there is so much fantasy potential in Luck that it’s so hard to sit him. His passing yards have increased in each game this season, but he absolutely has to cut down on the turnovers if he wants to continue to ascend the rankings. He is currently the 21st-best quarterback in fantasy football at this juncture, behind players like Matthew Stafford, Alex Smith and Ryan Fitzpatrick. Put this in perspective: He was one of the top two or three quarterbacks drafted this year in fantasy formats, and he is just a few points ahead of Brian Hoyer. Yes, Brian freakin’ Hoyer. In Week 8, Luck and the Colts will face a Carolina pass defense that has allowed the second-fewest fantasy points to opposing quarterbacks this season. In six games, the Panthers have allowed just five passing touchdowns, while intercepting the opposing quarterback nine times. Unless you have a better option, you have to start Luck in your lineup. Luck has thrown nine interceptions in five games and the Panthers have showcased a knack for intercepting the opposing quarterback. Luck will have his fifth multi-turnover game of the season in Week 8 against the Carolina Panthers.

The Case for Brees: Much like Luck, Brees has been far from elite this season. He has only one game (Week 4 vs. Dallas) this season in which he scored more than 20 fantasy points. The veteran signal caller has thrown for 300 or more yards in four of six games this season, so why exactly isn’t he ranked higher than the 20th overall quarterback through seven weeks? Well, Brees has just two multi-touchdown games this season but his 7.4 yards per attempt is a bit low. What do Alex Smith, Brandon Weeden, Hoyer and Josh McCown all have in common? Their yards per attempt are higher than Brees’. The Saints face the Giants this week, a team that has been decent for the most part against the pass. Among teams who have played seven games, the Giants have allowed the third-fewest fantasy points per game to opposing quarterbacks. The team’s 11 interceptions are tied with the Eagles for second most in the NFL, trailing only the Arizona Cardinals. Brees will start in many lineups, but in DFS, spend your money elsewhere.

The Verdict: Luck. He’ll throw for plenty of yards, and should find the end zone multiple times.

Running Backs

Chris Johnson (@Browns) or Jonathan Stewart (vs. Colts)

The Case for Johnson: Believe it or not, Johnson actually has the second-most rushing yards in all of football right now. His 567 yards trail only Devonta Freeman, who has rumbled for 621 yards and nine touchdowns thus far. As for Johnson, he doesn’t factor much in the passing game, but when you’re averaging 5.1 yards per carry, you’re definitely doing something right. Sure, David Johnson might swoop in and vulture a touchdown or two near the goal line, but more often than not, it’s going to be CJ2K that gets those carries. Through seven weeks, he has received 62.5 percent of the carries in the red zone and 60 percent inside the five-yard line. Johnson will face a Cleveland defense that was decimated by Todd Gurley in Week 7. The Browns have allowed a 100-yard rusher in each of the last three games and Johnson should receive the workload to be extend that streak. Seeing as the Browns are allowing an average of 146.6 yards per game to opposing running backs, Johnson is a quality play across the board in Week 8.

The Case for Stewart: Why does Stewart have just two rushing touchdowns on the season? Well, you can thank Cam Newton and Mike Tolbert, the human bowling ball, for that. Despite having the most carries on the team in the red zone, he is tied with Newton when it comes to carries inside the five-yard line. Although the touchdowns are few and far between, Stewart seems to be rolling and he has accumulated 44 carries in the past two games. His best two games of the season have come against two of the league’s stiffer defenses, the Philadelphia Eagles and the Seattle Seahawks. The Colts have been pretty friendly to opposing running backs, allowing the sixth-most fantasy points per game to the position. He’s expected to have another heavy workload and he will be in a ton of lineups in Week 8.

The Verdict: Johnson. The Cleveland Browns defense is so bad that it’s almost impossible to pass up Johnson this weekend.

Darren McFadden (vs. Seahawks) or Alfred Blue (vs. Titans)

The Case for McFadden: After seeing just 37 carries through the first five weeks of the season, McFadden toted the rock 29 times against the Giants in Week 7. His 152 yards in that game accounted for over half of his total production for the season. He was a backup to Joseph Randle early on, but McFadden will be the starting tailback for America’s team against the Seattle Seahawks in Week 8.  Everything is looking up for DMC, but he does face the Seahawks, the No. 2-ranked defense in fantasy football to date. Things aren’t going to come as easy for the Dallas running back in Week 8, but given the heavy workload he will likely receive, he is no less than a flex option in most formats.

The Case for Blue: With Arian Foster out for the season with a torn Achilles, Blue will likely get the first chance to be the bell cow back. However, Houston will likely distribute the carries more so than they did when Foster when healthy. Along with Blue, Chris Polk and Jonathan Grimes will be in line for additional work. However, Grimes seems to be more of a pass-catching only back, Polk does a bit of everything and Blue is virtually non-existent in the passing game. In PPR formats, Polk might be the safer play, but Blue has been the most efficient on the ground of the three backs. Don’t get me wrong, Blue’s 3.9 yards per carry average isn’t anything to really get excited about, but the best thing to do with this situation might be to wait a week before inserting any of these three in your lineup. Also, Tennessee has been pretty stout against the run, in fantasy terms, this season, so I’d wait at least one week before rolling with a Houston running back.

The Verdict: McFadden. DMC is the safer play between these two and he will likely see quite a few carries against a stiff Seattle defense.

Wide Receivers

Randall Cobb (@Broncos) or Alshon Jeffery (vs. Vikings)

The Case for Cobb: Before the team’s bye last week, Cobb had just 10 receptions (zero TDs) in Weeks 4-6. Through the first three weeks of the season, he hauled in 20 receptions with four being of the touchdown variety. Cobb was clearly dealing with some sort of pain in his shoulder, but the week off should have helped his ailment. However, a matchup with the Denver Broncos is far from ideal for Cobb and the Packers. Denver has allowed opposing wide receivers to catch just one touchdown this season, while averaging just 11.4 yards per reception. Aaron Rodgers is a good enough quarterback that he should be able to get Cobb the ball, but he’s going to blanketed by one of Denver’s two star corners. More often than not this season, Rodgers looks to Cobb, so a high volume of targets could lead to a respectable fantasy day against a stiff opponent.

The Case for Jeffery: The top wideout in Chicago missed four games with a hamstring injury, but he was able to return in Week 6 and boy did he look good. He hauled in eight balls for 147 yards and scored his first touchdown of the 2015 season. The Bears had their bye in Week 7, which provided Jeffery with some extra time to make sure that hamstring is at full health. Sure, the Vikings have been rather tough on opposing wide receivers this season, but I don’t think there’s a better time to play Jeffery than this week. In theory, he should be the healthiest he’s been all season since injuring the hamstring. Chicago will need to score yet again, seeing as they allow almost 30 points per game, tied with the Bucs for worst in the league. He seems like a good play this weekend.

The Verdict: Jeffery. As I mentioned above, it’s a great week to roll with the Chicago wide receiver. I’m all in on Jeffery in Week 8.

Stefon Diggs (@Bears) or Travis Benjamin (vs. Cardinals)

The Case for Diggs: Diggs’ name has exploded lately. He caught six passes for 87 yards against a stout Denver secondary before the team’s bye in Week 5. In the past two weeks, Diggs has caught 13 passes for 237 yards and one touchdown and he is showing no signs of slowing down. He has developed a nice rapport with quarterback Teddy Bridgewater and Diggs has become a solid flex option for many owners. Diggs and the rest of the Vikings will face the Bears this week, a team that allows the fifth-most fantasy points per game to opposing wide receivers. Mike Wallace isn’t much of a threat in Minnesota, so the door is wide open for Diggs to be the go-to guy, along with Charles Johnson, for the boys in purple. His price in DFS will likely rise, but this is a matchup that is definitely worth exploiting, especially given Chicago’s ineptitude of keeping the opposition off the scoreboard.

The Case for Benjamin: If Josh McCown plays, Benjamin will reside in the WR2 realm for this Week 8 contest against the Arizona Cardinals. All signs at this time point to McCown playing, but if he is unable to go, Benjamin drops to more of just a flex consideration. With Johnny Manziel at the helm (if McCown were unable to go) Benjamin is a boom-or-bust player who will have you jumping for joy or shouting four letter words at your television. In Week 2 with Manziel as the starter, Benjamin caught just three passes, but two were for a touchdown and he totaled 115 receiving yards. Against a Cardinals defense, however, things are going to be much tougher to come by. Although, to Benjamin’s credit, he did catch nine passes for 117 yards against Denver, who has arguably one of the best defenses in the NFL.

The Verdict: Diggs. He should continue to see his fair share of looks and his floor seems to be higher than Benjamin’s.

Tight Ends

Jason Witten (vs. Seahawks) or Larry Donnell (@Saints)

The Case for Witten: Oh, if only Tony Romo were healthy and under center for the Dallas Cowboys. The Seahawks struggle covering tight ends, but without Romo, Witten’s upside in this matchup is nowhere near where it could be. The Seahawks have allowed the second-most fantasy points to tight ends in 2015, but with Matt Cassel under center, Witten isn’t exactly a high-end TE1. If Romo were playing, he would be, but with Cassel, consider him more a low-end TE1 in this matchup. He has yet to record fewer than four receptions in a game this season, but he hasn’t caught a touchdown pass since doing it twice in Week 1 against the New York Giants. He’s averaging 13 fantasy points per game this season (PPR formats) and he will likely finish right around that amount in Week 8 against Seattle.

The Case for Donnell: Donnell hasn’t topped more than 38 receiving yards in a game this season, so why am I even mentioning him? The Giants’ tight end goes up against the Saints in Week 8, and he could be a big product of an easy matchup. New Orleans has allowed the fourth-most fantasy points per game to opposing tight ends, so Donnell could hook up with quarterback Eli Manning a few times over the course of this game. Don’t get me wrong, he’s surely a longshot this week, but if the price is right, the potential upside is worth the risk. For what’s it worth, he scored a touchdown in Week 2, and then Week 5, so if that trend continues of scoring every third week, he would find the end zone this weekend.

The Verdict: Witten. His role in the offense is more prominent than Donnell’s and that should translate into more success.
