What is the team's relationship with Coach Dunlap? I can't imagine it's any good. Looks like they gave up on him tonight.
To me, Coach Dunlap is bad cop. Look at his press conferences following are victories (rare as they are). Even then, it's never an acknolwedgement of any of the good we did in those games. It's always "do this better, do that, etc." Some guys may respond to that kind of talk, but most others probably won't go the extra mile for someone whom your work is never good enough for.
Lavin is the opposite. It's always sunny in his world, at least when talking to the media (I do think he points out corrections to the team, but maybe in a more calm manner).
It's a nice opposite dynamic that could work really well together (see Torre and Zimmer for all those years), but if you take one of those pieces away, the other gets exposed.
I want Lavin to get well as much as anybody, but it may be time to get him a weelchair, if that what it takes for him to come back to the sidelines soon. If he can't, make Chiles the head coach, and Dunlap goes back to assistant. That way, the communication between coach and player likley improves.
