This is such a tired cliche. Yes, building a "Program", meaning a sustainable group of guys with enough experienced depth to replace losses and still win 7-8 games a year, every year, takes a few years. No question.
But there is no excuse for year two of your rebuild being dramatically worse than year 1. There is no excuse for the kind of regression we've seen from this team. There are absolutely things you can do to win right now. K-State was once where we are, and they turned it around quickly by embracing JUCOs among other things. Randy made a mistake in my opinion, in deciding to play "his" freshmen. Anybody on the roster is his guy now and deserves to be treated as such. I think he even partially acknowledged it after the last game, saying he'd give more time to more experienced guys.
I'll put it more simply, Diaco, ever incompetent, used to win 2-3 games with his players. Certainly Randy could have and should have tried to merely bring competence to that situation, win 4-5 games, and work in his new recruits over time. He didn't need to set the place on fire.
