You left off every player we didn't redshirt that went on to be average. There are a lot of them to. I'm not saying every single player should redshirt. I'm saying that Rhoads has, ever since he's been here, wasted redshirts and in doing so it has cost us wins. You have to balance the season vs. the program, and even when his job wasn't on the line Rhoads hasn't done a good job of that.
Would our defense be better if Miller still was on the roster this year? I think the answer is yes. His light came on in the middle of last season and he'd have been very solid for us this year. Certainly better than undersized, underskilled guys who will be taking the field for us this season.
To use the most glaring example, was it a net positive to the program not to redshirt George? I'd say that playing George as a true freshman was a huge net negative for the ISU football program and cost us a minimum of one win over how many we would have had if he had redshirted. Possibly 2-3 wins. We don't go 2-10 last season with George running the defense. Give George a fifth year and he's for sure All Big XII, possible All American, and probably actually gets drafted instead of being a free agent.
Heck, I posted already about how he only had four tackles as a true freshman. It was worse as a sophomore. He has one tackle! 1! Good thing we got him out on the field as a true freshman so he could put all that experience to good use for that one single tackle as a sophomore.
