By cooler heads and knowledgeable fans, not carnes and the like.
I didn't see enough to think he should play in front of an electric player like Sams. Seems to hold the ball too long and didn't throw well on the run. That's my facile judgment, but would like to hear from those who know the game better than me.
That was my assessment as well. He seems to be more a pure pocket passer. I don't want to put the blame on anyone, but the offensive play calling was not suited for Waters. The delayed quarterback sneak that Klein was noted for needs to be scrapped if Waters is going to remain QB. He has absolutely no running ability and things are only going to get faster when league play starts.
I was a bit surprised that Sams did not get more play after the touchdown. Is he in the dog house with the coaches? Were they miffed at his celebration after the touchdown? Back to Waters.... If Coach Snyder is going to commit to him being QB, he has to develop a scheme to suit Waters' skills. Otherwise, even 6th place in the Big XII standings may look good by November.
