It amazes me the amount of arguing there is over Kaepernick. He is, at this point in his career, a total question mark. He has had some flashes of brilliance, and some absolutely horrible moments. The amount of praise and pressure heaped on him after he did so well once he took over was ridiculous, and there was very little chance he could live up to those expectations. There is no way anyone, outside of maybe the 49ers organization, that is going to claim he is a great QB at this point in time. Could he potentially be great? Maybe, we won't know for a bit still. I think there is a very real chance he ends up being a subpar QB that only hangs around due to his athletic ability.
I would still call him better than mediocre, and that is only because of his ability to run the ball and keep drives going that way. If you want to base it totally on his passing ability, mediocre at best is an absolutely fair assessment. I find it funny how passionate people are about the guy one way or the other.
Being a 49er fan I hope that he becomes great. But the reality is that I have zero faith in him right now as the guy to lead the 49ers to the Super Bowl.
