In response to ianboyextreme's initial comment/question:
It's not so much that the team is losing, it's how they're playing in general. Even their wins weren't pretty. People who understand basketball can look at the team's 4 wins and see victories over teams with a combined 5-26 record. Every talented team they've played they've lost to (and throw in NO for good measure). Pierce being injured or under-conditioned shouldn't equate to automatic victories, not when the Spurs can win without Manu and the Heat can win without James and Wade.
Even if they had beaten the Mavs last night (another .500 team, mind you), there would still be questions regarding turnovers, poor shot selection, poor conditioning, poor offensive efficiency, poor defensive rotation, the lack of any true center, their horrific rebounding numbers, and their propensity to fall behind by 10+ points in each game.
It's true that a win would have mitigated much of those issues for one evening, but those issues are still there, win or lose.
