My first inclination when I heard the Celtics had hired Butler coach Brad Stevens – and saw his picture – was that Danny Ainge had promoted the JV coach.I understand Butler has had fabulous success in almost winning two straight NCAA men’s basketball titles ? and that Stevens did this with a mid-major team playing with house money both seasons.He’s not playing with house money anymore, unless you’re of the opinion he’s been brought in here to preside over two intentionally wretched seasons so the Celtics can take their chances, get in the NBA lottery, and rebuild via the draft.I just hope Ainge knows what he’s doing. And what worries me is that I haven’t always been confident that he does. The last college coach he brought in here (Rick Pitino) was a disaster. And college coaches in general don’t thrive in the NBA, at least on their first go-around, because the ethic’s entirely different. The NBA is a players’ league. The NCAA shines its brightest light on the coaches.Word is that Stevens is the anti-Pitino. He was content to stay at Butler, having spurned offers from the likes of UCLA. He doesn’t have a huge ego. These are things that will certainly help him avoid the failure that defined Pitino in Boston. But whether that translates into a smooth relationship with Rajon Rondo remains to be seen.Most people are hailing this hire as a coup for Ainge. I’ll have to take a wait and see view of it.If Wednesday’s news wasn’t stunning enough, the news that the Bruins pulled the trigger on trading Tyler Seguin to Dallas was even moreso. At least to me.I don’t like this move. I think the Bruins have given up too soon on the kid. He had a bad couple of rounds in the playoffs, but think this is more than simply that. I think he, like Phil Kessel before him, is not Claude Julien’s type of player. And now that Julien has, once again, saved his job by getting the B’s in the finals, Seguin was the one who became expendable.GM Peter Chiarelli is acting as if the Bruins came in last place. They got within a game of taking the vastly superior Blackhawks to the limit in the Cup finals, and he’s blowing the whole thing up.The Bruins already lost one promising player (Kessel) to get Seguin. And now, they’re doing the whole thing all over again.This is absurd.Steve Krause can be reached at [email protected].
