I remember people unhappy with Eli and his performance over his first couple of years, but I never remember reading about wanting him cut, or even 'run out of town'. Very rarely do first round picks get cut in their first few years, let alone a #1 overall pick.
Jerigan is a #3 pick and probably a reach at that.
People are comparing the Cruz situation to Jerigen. It's apples and oranges. Cruz showed in a pre season game, when he was a rookie, that he had potential. That alone showed the coaches that there was something there to hold onto. Jerigan has shown NOTHING, in pre season, in any games he has managed to get into. He was touted as a punt returner, yet he can't do that very well.
I would love nothing more than for JJ to become an all pro when he gets a chance, but when is that chance going to be. Even a rookie starts over him when he has been here two years, knows the offense, yet still cannot break the line up. I don't care what position he plays, who he is playing behind, if the coaching staff thought he could bring something to the game, they would find a way to get him some touches.
When he was drafted he was labeled S Moss II, and he has lived up to that billing.
