I would erect a guillotine in the middle of the field and march ol Jonesy boy up there. When he's got his head beneath the blade, I'd unfurl a scraggly old parchment and enumerate all of his offenses against Cowboys Nation. Then it would be off with his head. :)
He did that several times in the Lions game, with disastrous results.
I think Dez shoots all his adrenaline in the first half and is burned out in the second. He needs to tone it down, clear his head, and just make plays.
