I see some people saying Kapernick can't keep doing all that running or he'll wind up like RGIII.
Those people need to do their research. RGIII is built like a WR. Kap is built like a TE... 6'4 at least and around 230 lbs. Pretty sure he can take a few hits and probably dish some out too.
He's gonna be a tough customer for that Falcons D that laid a huge egg in the 2nd half of their game yesterday. Especially on that fast track in the Georgia Dome.
