Is he though? He beat up on the SWAC East and lost 2 straight bowl games to MEAC schools. He was able to outrecruit that level of program and then he brought several of those players to Colorado including his kids.
Last year they were more competitive against the bottom echelon of the PAC-12 but they got stomped by Washington and Oregon and needing to beat a bad Washington St. to keep bowl eligibility alive they no-showed and got stomped again.
He's doing a better job of recruiting than his predecessor certainly, but IDK if that constitutes doing a "great" job. Particularly when you consider how many of the old players he got rid of and how many of his new recruits came in during the hype of year one. It wasn't a typical year one where he recruited freshmen and you're waiting for them to grow with this year's recruits etc. He straight up poached whoever he could get his hands on and that got him 4 wins. Will they be better this year? Maybe. They certainly have a weaker schedule which will help them.
