Just for reference, here is the call in question. It is around the :34 second mark
Now, if they called an unsportsmanlike conduct penalty for him reaching out as if he was going to help the defender up, and then pull his arm away as the defender extended his arm to grab #96 hand, I could sort-of see that. I wouldn't completely agree with that, but I could see it. But just straight up personal foul? If they are calling it on the hit, what, are football players not allowed to brace themselves when somebody is trying to take a cheap, but legal shot at them? It almost looks as if the ref didn't see the whole thing and just saw a blue jersey flying to the ground, and a white jersey walking with a little swagger. Bad call. I'm glad they were suspended....they were supposed to be the crew for the UT vs UA game this weekend. Not sure how true that is, though.
