Agree. With big, strong Midwest linemen and big running backs they could perhaps be one of the if not the best ball control offenses in the Big 12 but instead they are consistently one of the worst "high power" offenses.
And I think the Fatman should get fired before Burnham does fwiw.
It's a bit of what Snyder has done in recent years at K-State. With Klein at QB, he used a good OL and a great powerful running QB to control and dictate the pace of the game. He tweaked it a bit with Waters at QB, but same principle.
It's not a winning formula for Iowa State to out-athlete Baylor, TCU and Oklahoma by going spread and speed up. It would be like Iowa trying to beat Ohio State by running Urban Meyer's offense. It's a losing battle, as OSU will recruit the better athletes. Note: It's not like Iowa has had much success against OSU anyway, but Iowa has at least had numerous competitive games against OSU under KF.
