Iowa State got turned around by recruiting tall guys and hanging weight on them, slow or not. Bum Phillips was quoted once about a good big man beats a great little man every time.
Different level of ball being played, and a different set of expectations.
For instance, we crucified Butch Jones for losing at South Carolina by 3 in his best season. Matt Campbell lost by 17 to the Rajun Cajuns this year. At home. The Big12 isn't really a power 5 quality conference, and their annual OOC drubbings and losses against FCS opponents essentially make that irrefutable. He deserves credit, but Iowa State would be lower than Vandy in the SEC. Otherwise, he's gifted 3 conference wins against 3 of the worst programs in D1 with Kansas, Kansas State, and Baylor.
