Rim protector my ass. Way too much talent to lose 10 games, rim protector or not! The defense that Tom Davis ran WAS the problem. Sorry. Tom Davis was an average coach, at best.
Oh, there was much more than that. His point man in the 1-2-2 was often lazy getting out and identifying shooters at the top of the key.
His entire defense was lazy at getting out and identifying shooters.
His substitution patterns often seemed scripted, with no rhyme or reason to what the flow of the game dictated.
He was a horrible bench coach, in game coach, and end of game coach.
His offense was horrible at setting screens, a death notice in a physical conference like the B1G.
Speaking of being physical, his aversion to weight training further set the team back in the battle to be the stronger team on the floor
He averaged 25.7 wins per season with Raveling's recruits, sans Jepsen's senior year, and was 6-3 in postseason play.
He average 19.2 wins per season without Raveling's recruits, and was 7-6 in NCAA play.
You've talked about the talent on the floor. You haven't even mentioned the talent on his staff.
My original list wasn't inaccurate, just incomplete. He had his good qualities as well of course, but truth be told his finest hours as a coach were at Boston College.
