1.) I believe Colt McCoy will have a legitimate chance to prove he can be a starting QB in the NFL, but can he do that right now? No. He just isn't as physically developed yet.
If anyone looks at McCoy when he was a Freshmen, he was under developed physically and put on 20-25 Pounds of Muscle. My guess is, that he is doing the same this season also. McCoy has the tangibles, now he needs the frame and experience to get it together. Holgremn doesn't want to play a Rookie QB, then tell me one person on this forum that has more experience, knowledge of football and respect then Holgremn has right now? That's easy, none of us have that.
2.) We are NO WHERE EVEN CLOSE to waving the white flag as you suggest just to see what McCoy has. 1-3 in 4 close competitive games does not scream (put in the 3rd String QB).
