Most of that reputation, so far as I can tell, comes from media figures, with whom he had a contentious relationship or simply follow along with what's focused on - yelling, anger, smarts comments to reporters. Most players seem to feel differently and believe he makes them better hockey players.
Sure, he has a shelf life, like most guys with that kind of personality, but I do believe he's toned down a bit from his younger days having been out of the league for a few years.
I guess I just believe the media's construct of Torts is vastly different from reality, but at this point it has a life of its own. Hopefully he can have success here and create a different legacy.
