Who cares? It's a meaningless regular season game we won. And who can blame the players if they don't play every regular season game like it was their last? Management has come out and said again that certain players would be playing if it's the playoffs, but that they aren't right now because they're playing it safe. Translation: the regular season doesn't matter. If management is sending that message, it's hard to blame the players.
More importantly, this romantic notion that all champions played each regular season game like it was their last is a crock of bull. The Shaq/Kobe Lakers and the Duncan Spurs teams clearly paced themselves during the regular season. More importantly, while Larry Legend certainly had a killer instinct in the playoffs, it wasn't like he killed himself (particularly on the defensive end) every regular season game.
