As far as Coleman and other young redshirted players go, after the OSU game they could start playing them all some and still preserve their redshirts (at least those that haven't played in any games yet). We might see some of that happening once we are down to 4 games left on the schedule. I believe I read that if we make a bowl game, playing in that does not count towards to 4 game counter (could be wrong on that), so they could play in a bowl game also I think.
No idea if Coleman has improved this fall, but it is at least a legitimate thought that we could play some of the redshirted guys the last 4 games of the season. At the very least, to start getting them game experience, and maybe some of them would actually add positive things to the offense (or defense depending on the player).
