Sometimes rule changes are good for football, such as aggressively calling defensive penalties allowing teams to have more success than ever tossing the pigskin. Other times rule changes have negligible value, especially when it comes to their weekly influence on fantasy football. The NFL made two significant changes this offseason when it comes to special teams play. Football will be more exciting and frustrating than ever in 2015, but what do these changes mean for the fantasy universe and team defenses?

1. Extra point attempts will now be from the 15-yard line making them 33-yard kicks instead of 20-yard kicks. Last season, extra points were converted at a 99 percent rate making them as automatic as my ability to get a girl to spend the night at my place after buying her four Mai Tai’s at a bar on Saturday night. Kicks from 30-35 yards were converted at a 95.3 percent clip, or akin to my lady conversion rate on a Sunday night (the rate is about 94 percent the last decade for making field goals, not my ability to “score” on Sunday nights). That’s a slight difference, but not a statistically significant one. Practically speaking, there may be a few more two-point conversion attempts, especially if the weather is a bit dicey.

2. A defense can return a loose ball or interception on a two-point conversion attempt or an extra point attempt for two points by returning the kick to the other end zone. This is likely the biggest difference to consider in terms of a fantasy impact. If an average team defense scores ten points a week, then we’re talking about a 15-20 percent boost in potential weekly points with one return. This could result in weekly matchups dictated by the rules change because we all remember times we lost a matchup by one point or less. The rule change also offers the potential for extra points for people in IDP leagues.

You might be thinking we should pay more attention to selecting team defenses because of these new rules, but how do you change the way you look at them? Can you predict which teams will have their extra points or two-point conversions be unsuccessful? Of course you can’t. Similarly, you can’t possibly know which team defenses will benefit the most from these rule changes. It might make for more exciting games on TV and play a huge part in some weekly matchups, but there is still no way to predict how or when a defense will score this way. It is just another level of uncertainty when it comes to team defenses.

Finally, do not be that person who takes a team defense first. Every year people claim to know which defense will be the best, but they are almost always wrong. Being a good NFL defense doesn’t always translate into being a good fantasy defense.
