Giants 1st-round pick CB Prince Amukamara garnered the 3rd-best rating among rookies in Madden '12. That might just seem like a fun, relatively worthless tidbit.  But IDP owners should take note as they consider drafting Terrell Thomas. The CB has been a fantasy beast the past 2 years but could be overvalued in 2011. CB tends to be one of the easiest positions for a rookie to pick up. If Amukamara can get quickly up to speed, he could displace Thomas in the lineup early this season. That wouldn't kill Thomas' fantasy value. Teams put 3-CB packages on the field often, and covering slot receivers would help Thomas' tackle numbers. It's enough to make you think twice about drafting him 1st at the position, though.
