The Todd situation was well documented not much debate about the facts with video/recordings being a turning factor in both his rants and contact with player. The was no he said/he said - there was just coach and reality of what he said and did.
Sorry but any coach loses the benefit of the doubt to "accidently" have physical contact with a player AFTER he has been under suspension for 1/2 of the prior season for misconduct.
To the extent any misconduct as the GF Coach disqualifies him as a showcase coach I think not - as long as parents and players are aware of his history and have asked any questions and received satisfactory responses.
In this regard another Chesapeake coach is experienced in dealing with past problems - Bobby Hoeft. Situations are not equivalents but Hoeft (like him or hate him) does address his past openly.
It might be tough to imagine a world where kids grow up and play sports and don't have a run until you puke story to tell but that is where we are heading. Everyone should have a little faith that every change from the past is not the end of civilization.
