This is just the Bennett's MO.
His dad quit mid-season at Wisc.
His dad anounced he was retiring from WSU before the end of the season.
TB abruptly quits in the pre-season. No official games yet, but certainly the team is engaged fully at this point.
Might be a way of forcing the University to pick one of his assistants. Of maybe something snapped (or about to). Dick Bennett was supposedly on the edge of a nervous breakdown/exhaustion/burn-out at Wisconsin. Seems like since TB has spent his entire life in basketball, he would know what he was getting into at the start of a season and could have decided in the summer whether to return or not...
