24-year old RB Adrian Peterson had another outstanding year for the Vikings in 2009.  He played in all 16 games for the Vikings last season and he carried the ball 314 times for 1,383 yards (4.4 ypc) with 18 TD runs.  Peterson also caught 43 passes for 436 yards (10.1 avg) last season for the Vikings.  Peterson really benefitted from having Brett Favre at QB as opposing teams couldn’t load the box to stop him.  Peterson has now played in 46 games in his career with the Vikings and he has carried the ball 915 times for 4,484 yards (4.9 ypc) with 40 TD carries.  He has also caught 83 passes for 829 yards (10.0 avg) with 1 TD grab in his career.  The knock on Peterson coming into the NFL was that he was a tad injury prone but he hasn’t really shown that in the NFL.
