re: Anyone know why Orgeron reacted so strongly to the Pete Carroll/Jerry Sullivan question?

Same reason that Saban does it. You know in advance who's out to ask "gotcha questions" or is an enemy of your staff..so when they do ask question, you humiliate them and make sure they stick to real football questions when in that setting.
His point is that we have a coach that a Super Bowl winning coach asked to attend so his professional staff could learn from Sullivan. Write about that! That's a big deal.
