This really boils down to what everyone's opinion of a good coach is. Some favor the do more with less, other think recruiting is part of coaching, so why should a coach be punished for that.
All I know is, Bill Self just won his 11th straight league title, in the toughest league in the country, with probably one of, if not the least talented teams he had. He did something no one else did in the league, and that was he didn't have a bad loss. And on two occasions I saw them come back from more than 15 points down to win, neither time did the other team really buckle, but self coached his guys up.
I love Hoiberg and I wouldn't trade him, but in my mind Bill Self is still the best coach in the B12, and I have no problem with him winning coach of the year. When Hoiberg figures out how to not have let downs like TT and give away games like KSU, yes that was the coaches fault that inbounds play was absolutely atrocious, then he can be the best coach in the league. But until then that title stays in Lawrence.
In all the years of the B12 this is probably the first year, you can say the league was so tough whoever comes out on top, was the best coach. Other years I think you could argue, Drew or Huggins, but way to many chances to get blown up along the way, the team that navigated that best during the year, deserves COY. Just my opinion.
