One more interesting side note about this team under Stevens is that: I can't pick out anyone, player or coach, as being outwardly negative. Even Crawford has become a consummate professional. Not so coincidentally, his game has taken off.
This year, they have made an obvious effort to stay away from complaining or criticizing each other or the refs. As a result, the chemistry is flowing and they don't have drama surrounding them. It is allowing the team to grow as a TEAM and just keep improving.
Just another explanation of why Brad Stevens is a fantastic coach and gets so much out of these guys.
