I don't see what needs to be determined about Kaep. If he can make it in all those pressure games he can make it in any regular season game. I'm not talking about nothing to lose throw the ball all over the place clutchness Luck. I am talking about being 17 points down in an NFC championship against a juggernaut offense and coming back easily and beat them clutchness. Give Kaep some credits now. If you can do it in those type of games a 16 regular season is nothing.
RG3 honestly is probably not going to be in the league in 10 years. There is no way he can sustain a career where he is a running QB at his size. I think that honestly everyone that knows football would say it is Cam/Luck at 1a 1b. Kaepernick has played 10 freaking games. Nobody knows his strengths or his weaknesses. As soon as that is discovered he'll be limited with what he does.
Wilson IMO is closer to Cam and Luck than the other two b/c he isn't reliant on running. Those three are the three who can make a living as pocket passers. Especially if Cam shores up his accuracy on short/intermediate throws. TBD with Kap b/c of sample size.
You say Kaep plays only 10(+1) games, well the other rookiees only played 17. 6 more games? Really? The guy is in the superbowl.
