I'd give them an A. The Lakers have set the bar with three finals appearances and two chips in the last two years, so they're an A+. Boston's been the second best team in basketball over that span, and if it weren't for a KG bum knee they might have another championship in the bag.
RE: perkins. That deal hinges 100% on the health of Shaq over the course of the playoffs. Right now it's looking like a bust. If Shaq can come back and stay healthy in the playoffs, they'll be the team to beat, and the Perkins deal will look pretty good.
