It has always been said that NFL rookies will eventually hit that dreaded “Rookie Wall” at some point during their first season. These rookies are used to playing 12 games throughout high school and college, so between the weekly grind of playing 16 games in the NFL, as well as learning and going through so much both physically and emotionally, you can see why many rookies struggle to complete a full 16 game schedule and perform just as well in the second half as they did in the first half of the season. We saw it with Cam Newton of the Carolina Panthers last season, and it appears we are seeing it start to happen to Robert Griffin III with the Washington Redskins in 2012.
The same, however, cannot be said of Andrew Luck of the Indianapolis Colts and Doug Martin of the Tampa Bay Buccaneers. With each passing game, these two seem to only get better.
Well, with each running week as it pertains to Martin.
