He is definitely NOT a great passer. He was a decent QB at one time with oodles of upside. But, anyone who saw him play last year could easily see that he has fear in the pocket. He doesn't step into his throws like any good high school QB does. It certainly looks like fear of ruining his knee again.
Does anyone remember reading the observations of RG by their former TE, Cooley. He basically called RG the worst QB in the league.
I'm not an EJ guy, but I wouldn't trade anyone of our QBs for RG. I hope for his sake that he somehow gets through this dark time of fear in the pocket.
