When I first heard of this story, I almost fell out of my chair (which is dangerous because i was driving at the time).  None of the behavior described seems like something Krenzel would do (based on my limited knowledge of the guy), but I wouldn't put it past any parent if they felt their child was being endangered (or roughed up at football practice sans helmet). 

Interestingly, Cowboy Craig was left off of The Fan yesterday afternoon (he had been filling in for Common Man all week).
