I've been sifting through most of the pages in this thread and saw a recurring sentiment; RG3's playing style will ultimately shorten his career. What I say to that is.... perhaps. The possibility will always loom when he's outside the pocket with bodies flying around. However, playing QB in general will ultimately result in many injuries throughout the course of a career whether pocket passer or scrambler. The threat of a season or career ending injury is ever present for the NFL signal caller (Troy Aikman knows what I'm talking about).
Most rookie QBs go through the bumps in the road associated with learning how to minimize mistakes while operating an offense. In RG3's case, he's pretty damn consistent already operating his offense....it's him learning how to take less bumps in the road regarding his body. Pain is the greatest teacher and sometimes a young guy who thinks he's SuperMan has to learn the hard way. However he is learning nonetheless (the first injury this season came from just being reckless outside the pocket. The second injury occurred from not sliding fast enough to protect the whole body). RG3 is a smart a guy; he'll learn from it all.
And by the way, he's slated to play Sunday at Cleveland in a brace (he still has that rocket pin point arm).
