I don't see why Robinson won't be ready. He's been in the system long enough now and has been sharing practice reps. with Kenny. Look at Iowa State for a reference - Park leaves, Kempt goes down, then Noland comes in even though OSU barely beats them, they still scored 42 points on OSU and none of those 3 QB's were as highly recruited as Robinson. Expect Robinson to play good. TT is a little weak on defense so it should be a good start for him.
High school and college ball are two different games -- just like college football and the NFL. It's virtually never an easy transition. Even Andy Dalton struggled during his first two years at TCU (at one point, Patterson benched for throwing too many interceptions) and only shined during his junior and senior years.
I can't understand you guys who think we can just throw a green star-HS QB to the wolves and he will magically transform into He-Man. It happens on rare occasions -- but VERY rare. For every Manziel or RGIII or Mayfield you can name, I can show you 30 or 40 who completely fizzled in their first few years and later failed completely or didn't become at least moderately successful until their latter years in college ball.
Too many are looking for the quick-fix, the miracle worker. Reminds me of when Texas Tech hired Chad Glasgow from TCU to try out the 4-2-5 defense there, thinking it was just a formation defense and any coach knowledgeable in it could just install it at Tech and get instant success. Plug-and-play.
They learned better. Even when Gary Patterson installed the 4-2-5 at TCU, it took him 2-3 years to get the right players at TCU and train them in the strategy and progressions that made it successful.
Shawn Robinson is our future and nobody is wishing him any greater success than me. But we owe him a better chance than starting against a potentially dangerous opponent playing for bowl eligibility in their home stadium, where visiting teams have a poor success rate, and facing a really hostile crowd. I do think he should see some playing time. But if Kenny Hill can start? He should be our QB.
