#88 on the Panthers deliberately caused a defensive PI call around the 2 min mark in the 4th quarter. #32 for the Patriots is sitting there with his arms extended, and is backing up. The Panthers TE held the DB's shoulder so tight that the guy couldn't get away. It was offensive interference, holding in fact!!
The ref called it on the DB, but I'm telling you, I think the TE should be ejected for cheating, that's definitively unsportsmanlike. Watch that play again, and you'll see what I mean.
All that being said, I hope the Panthers win this one.
