I don't think anyone is saying TO is NOT productive. Even Chuck Pollock said on Bills Fan Radio last night that TO is one of the standout receivers in the league. But if you have any common sense at all, you have to air some caution and be weary that even though he can make some astounding plays, he also has a history of publicly calling Jeff Garcia gay, publicly saying Brett Favre could do better than McNabb, and publicly saying that Romo was going behind his back and drawing up plays with his Tight End. Which is essentially throwing 3 quarterbacks under the bus. He also demanded out of San Francisco and demanded out of Philly. This guy also stirred a media circus trying to get out of Philly and did situps while fielding questions without a shirt at his house?!
No one's questioning his work ethic or play-making ability, that'd be foolish, but you have to be cautious because certain things always seem to happen eventually anywhere he has played.
Hope this helps!
