"Go" sorry to use Socratic method here but why was DJ hired--that is what particular skills/abilities/knowledge/qualities does he bring to the table ? Frankly I think that answer is rather simple and does not involve being former player/grad assistant. Is the answer leadership ? I knew I could get something correct today. But certainly Hayes/Johnson will be comfortable with that.

Now I'm not suggesting there will be dissension in the coaching ranks just that Hayes/Johnson expectedly may be uneasy and slower to embrace the situation.
