I'll be honest, I was somewhat shocked that Snyder didn't pull the trigger and fire Zorn after last week's humiliating loss. I'm not sure there's any benefit to waiting, but he must be very very confident the Shanahan hiring is a done deal. I also have to think that Snyder remembers the beating he took when he dumped Norv before season's end. Although I doubt there'd be any outcry in this case, he may just not want to deal with potential criticism. The other factor could be that Shanahan has asked Snyder to wait, out of respect for Zorn. I think that could well be the case.
