I think if this team's strategy now is trying to do just enough to get the win, that's going to be a recipe for disaster. They're playing NBA teams, and not all that much separates the best and worst teams. On a given night, any team can beat any other team. Doing just enough to get the win will force you to play harder, ironically, because instead of blowing out a team and resting your starters, the game will be close in the late going, and your opponent will be given hope by the closeness of the margin.
I just watched the first half last night, but was alarmed at how apathetic the Celts looked in the second half of the second quarter, giving up most of a dominant 28-point lead. It doesn't sound like they brought much fight out after halftime either. If there was an award for "Cheese Dick Loss of the Year," this would be my candidate, easily. The Celts have lost games they shouldn't have this year, but this is the only game I can think of where they came out, showed clearly they were the superior team, then just pulled the plug on the effort level and let their inferior opponent beat them over the head.
