Obviously the odds are stacked against him, the likelihood of him being successful are slim but not impossible.
I for one am very excited for sunday and will be ready for whatever happens. I expect some mistakes and some first start jitters. Hopefully he doesn't implode.
My biggest fear is they have an unbelievably short leash on him and I think that is not the right way to go. Now I'm not saying throw the ball forty times but give him the shot he deserves to prove whether or not he can be a capable QB.
