If UAB coach Mike Davis is missing a son ...
... I think I may have located him. Florida State guard Jason Rich is a dead ringer for the fiery former Indiana coach. Especially when Rich gets that intense stare and flares out his nostrils just like Davis.
Unfortunately, I haven't been able to find still photos that can confirm this. Rich is smiling in his shot on the Seminoles' team website. He looks like a different person.
So you'll just have to watch for this on television or trust my astute judgement. Obviously, I'd go with the latter.
