I look at this 2 ways........first I can tell you it is complete bull$hit the way ND handled the end of that game. If you have ever played in a contest where your opponent is pulling that kind of crap, and then you are expected to turn around and shake their hands and tell them good game as soon as it is over, then you know that is a hard thing to do. Hard for me to blame Fran there.
The other perspective I have here......and this is why I think Fran will look back and regret this after he cools down......is that this young team, who is starting to get on a bit of a roll, does not need any negative energy right now. Maybe this will end up being no big deal, but it could have been completely avoided.
There are other ways to get your point across. Go through the line, give a terse handshake and a FU through your teeth to the Coach.......then immediately inform your AD that they are no longer welcome in Carver, and if you feel strongly enough about it, badmouth them to other Big 10 Coaches so maybe they hesitate to schedule them as well.
