It hasn't been as bad lately, but go back to the early 2000's and work your way forward. Even lately when injuries haven't been as rampant, the team's have been cursed. (Lions last season, Saints/Seahawks 2011, etc.)
I voted for AP, I know Foster has wanted to win this for 3 years straight but I will not offer him to God's favorite sports/video game joke that we call the Madden Curse.
Bad news is Arian lost but good news is the Texans will not be cursed. Barry Sanders (old school) vs. Adrian Peterson (new school) in the championship finals.
Not surprised with Petersons MVP year. The dude could go down as one of the top 3 RBs ever...if Foster can have his usual TD production and a 1600 to 1800 rushing year with a 4.8 ypc season or better, then he will be "with" AP and that's only a maybe as long as AP comes back down to earth.
