I think Danny's analysis is right on point: he's neither overreacting nor underreacting.
I'm also with footey, that Doc has got to take a different approach. No use thinking about a coach-change though: I can't think of another coach who could better reach the 10-14 year NBA vets on the team, plus Danny and Doc are joined at the hip. Maybe the Brain Doctor should secretly observe the halftime lockeroom via hidden camera and make some suggestions?
In these 8 games against crap teams, I'd like to see Doc sit on the bench, promptly, any starter who isn't putting forth the effort. If we can't beat a 5-win team with some backups playing big minutes, it'd be good for Danny to know that going into the offseason.
The problem with this, however, is that Danny took too long to get a backup PG, so Doc really can't sit Rondo, and Rondo is a huge part of the problem. I'm not agianst Nate as a change-of-pace PG, but he's the kind of guy you have to work in during training camp--he's too idiosyncratic to just plug into a standard line-up mid-season.
