Seems like Refs started getting really personal with the celebration calls after some defensive player, I don't remember who or for whom he played, did a "throat cut" gesture after sacking a QB. Really got the PC people crowd going, and refs can't keep that flag in their pockets since.
Still pissed about the call on JPW against LSU (phone gesture), right after Tebow had done it a couple weeks before. Surprised JP didn't get a flag after the Arkansas player got in his face and JP just pointed to the scoreboard (08).
