I didn't see it. Did the Bucs go after Eli on a kneel down? If so, that's just a breach of etiquette, nothing more. Etiquette dictates you lay down if it gets to the kneel down stage of a game, but nothing forces you to do this. In other words, I don't fault TB for going after the QB on a kneel down, though I don't condone it. If you're beat and it's kneel down time, just accept it and look forward to next week. I'm sure they were pissed that Eli got lucky a few times in that game.
But seriously, it's gotta be really tough accepting a defeat in the fashion the Bucs did.
