As we roll into the 2012-'13 NBA season, we're going to take you through an overview of each of the six divisions. Who are key newcomers? Who are notable for your fantasy team? Last season was brutal with a late and sudden December start to an abbreviated season. We continue our previews in the Western Conference, with a look at the Southwest Division. San Antonio's big three are back for another run, do Manu Ginobili and Tim Duncan have anything left in the tank? The Memphis Grizzlies continue to ascend and may be poised to take over the Division with Marc Gasol and Rudy Gay among the best in the West at their positions. O.J. Mayo is finally showing his potential, but can Dallas stay competitive until Dirk Nowitzki returns? Wow, that's all I can say about Houston and new leading man James Harden. Lastly, New Orleans rebuilds around Anthony Davis but the process has a long way to go.
