At the end of the Purdue game, after the clock ran out, a Purdue lineman hit a NIU player who was on the ground in what was a very late hit that appeared to be an intent to injure. He was given a personal foul (meaningless given circumstance).
If Purdue does not take action, does the Big Ten step in again or is there something about a punch (no matter how weak) that causes them to act. I think the Purdue incident was more likely to cause an injury.
I think it will be interesting to see.
