As to the original question...
I think it's to our ongoing favor that tough defense is part of our team identity. We have played this way all season, for the most part successfully, and done it before refs from other conferences, on others' home courts, and in tournament play--not just before SEC refs.
Now, if physical play was something we had pulled out of our hats for one game in order to compete against an otherwise superior team, that would (properly, IMHO) not stand.
But at the Sweet Sixteen level of The NCAA Tournament, the refs would become the story if they took away a team's season-long identity, which got them into the tournament--and not as some 16th seeded afterthought.
