Mike Tomlin challenged Mason McCormick last week to live up to the legacy of wearing No. 66. Based on his play against the Cincinnati Bengals, I would say he more than responded. McCormick looked great.
Perhaps the best trait a rookie player can have is the ability to learn from their mistakes. The more coachable they are and the better they adjust has a huge effect on how productive they can be as a rookie. That is especially the case for a player who came from FCS football against lesser competition. Even the least talented NFL players Mason McCormick goes against right now are miles ahead of most of the best players he faced while at South Dakota State.
