Not to hijack this thread, but this makes me ask a similar question: If a coach picks up a chair and slams it straight down (not throwing it Bobby Knight style), automatic T? How about if he lifts his feet high enough and stomps down on it really hard?

Reason I ask is that Bob Erickson (now retired coach from Doane College in Nebraska) was famous for doing the aforementioned antics. Most of the officials that worked those games usually let it slide because he did it out of frustration at his own players and never because he didn't like a call by an official. However, there were a couple of officials who T'd him up the very first time he did it in their games, and a couple of others who would T him up if he did it while Doane was on defense. I'm just curious everyone's thoughts on this.
