I mean there was a bit more too it than that (although I listened to the 2:14 clip).
He talks about reaching out to fomrer coaches to try and develop ways to get Tony to listen and ways to relate to him. the comment about taking the extra penalty (yelling at the ref) while already down a man talked about Tony's inability to control, or at least correctly channel himself and his 'street-fighter' personality. He references his believe that Tony needed more time putting in the hard yards in the AHL to develop some fortitude and maturity, which coach believes would have made ADA a more well rounded player than the guy we see now how can run a power play (or power plant) but maybe hasn't really got an all round game.
It seemed to tie in with everything else we've heard/read from NYR and other places. Tony is a good guy, you want to like him and 95% of the time hes fine. The issue is that the other 5% of the time he's off charts compared to most other people and so when he decides its time to go, no-one can talk him out of it and ends up making situations a lot worse, something that could be overcome with a bit more maturity and humility.
