I realize this seems to be a trend with John Beilein teams...it's either feast or famine in terms of offense because of the lack of a big man most of the time. I don't remember the defense being this bad overall ever though.
Something has to give though. I don't know if it is fair to say he's on the hotseat just yet, but defense has to improve next year and recruiting has to improve.
Izzo had quite the stretch during the 2000s where they were pretty mediocre. I don't think Beilein should be on the hotseat, but improvements must be made.
