Watching Allen on the sidelines pumping up his defense last week showed his leadership. By playing, he'll learn a lot more about reading a defense than he would holding a clipboard. Having a vet to help him would've been huge this year and IMO, more valuable than a 5th round draft choice and extra ST player.
Considering he probably has the worst line and WR corps in the league will hold him back this year, but IF they get him some blocking and receivers that can separate and catch next year, watch out. The sky can be the limit with this kid, may the schwartz be with him.
