ooooooooooh....so we're selective on who can talk trash.
Of course we are.
Lanky can talk trash all day about Jason Campbell or Dan Snyder and hell, I might agree with him, but if a Cowboy fan comes on here and starts it up I'm giving him holy hell. You're damn right I will. And so would you, because we may fight amongst ourselves in house but when someone from the outside says something we circle the wagons.
Yes, it absolutely matters who says what and one of the cardinal rules of team sports is you don't talk trash about your teammates. Players who do get (rightly) labelled team cancers and are sent packing, even if they have gobs of talent. Someone else mentioned TO. The ONLY reason that a guy who plays that damn well has been on four different teams is his mouth.
Over the years I have been a HUGE Portis backer. I have gone 15 rounds on various boards for him many, many times. But even I can see that Portis has now entered TO territory. He publicly called out his quarterback and every player who's gone on record has sided against him. That's reflects extremely badly on Portis.
He's dug himself a huge, huge hole here. I'd be shocked and amazed if he was on the roster at the start of camp.
