“When Garnett was injured, Boston was 44-11 and had an efficiency margin of +10.4 points per 100 possessions. Since then, Boston has gone 15-8 with a margin of +5.8. The offense has barely dropped (113.2 offensive efficiency down to 112.9) but the defensive efficiency has risen by 4.3 points. That’s the effect of Kevin Garnett. With a full-strength Garnett, the Celtics are right there with the Cavs, Magic and Lakers. Without him, they’re at the approximate level of the Blazers or Spurs.”
That’s about it in a nutshell, which is why it wouldn’t be surprising if the Celtics eased Garnett back into the lineup in the first round. Without him they are still one of the top seven or eight teams in the league, but they will certainly need him if they are going to successfully defend their title.
Also of interest: The Magic are reeling  and Hedo Turkoglu  and Rashard Lewis are not expected to play tonight against Milwaukee. Lewis has tendinitis and Turkoglu sprained his ankle over the weekend, but X-rays were negative and Turk is quoted in the story as saying the injury is not serious.
