12. Adrian Peterson
The Minnesota Vikings selected Adrian Peterson with the 7th overall pick of the 2007 NFL Draft, and it’s safe to say at least four of the six teams that passed on Peterson will be kicking themselves for a very long time. Peterson will go down as the second best running of this century, only behind Hall of Fame running back LaDainian Tomlinson. Of course, Peterson appears to be well on his way to a first-ballot induction into the Hall of Fame himself. He’s been named to the Pro Bowl seven times in his 11-year career, and either First or Second-Team All-Pro in seven seasons as well. He has led the league in rushing three times, led the league in rushing touchdowns twice, and holds the record for the most rushing yards in one game (296). Even with all those accolades, his most impressive feat might be rushing for 2,097 yards in 2012 only months after tearing both the ACL and MCL in his knee, en route to winning the league’s Most Valuable Player award.
