You know guys, this team cannot be very fun to coach right now. You have Cat auditioning for a big contract, Bobby out of synch, Bibby listless, Peja turning into the "Playoff Peja", about 6 undersized power forwards and centers, and a bunch of young guys new to the playoffs. Oh, and Ostertag. Sloan always had a blast coaching that guy.
At a certain level, you're right, Adelman's going through the motions, but so what? They're not winning this series. They might steal a game on the home floor, probably Game 4 to avoid the sweep, but I would be shocked if they picked up these two home games. I know that's pessimistic (sorry), but let's face facts.
And besides all of the above, the playoffs is about the players and player leadership. An NBA coach earns his pay during the regular season by instituting a defensive and offensive scheme and managing egos. Adelman is one of the best ego managers in the business, but has had no time to put in his schemes. If Miller/Bibby/Peja don't feel like performing, there's nothing he can do about that. This isn't the college game, even Peja makes 3-4 times what Adelman gets. Their will to win has to come internally. They don't have it this year, and Bibby is the only one that ever really did.
