He slammed his head, was examined by the neurologist on the sideline, and then taken to the locker room. That's a lot of theater to get yourself taken out of a game. Especially on national TV. I suspect we'll hear he has a concussion.
If you need to satisfy a narrative that he was embarrassed and pulled himself, have at it. I think that's as wrong as wrong can be about Taylor. He's a lot of things, he's not a quitter. Why didn't he ever do that in Buffalo? We all know he had his share of epically bad games, several on national TV.
