Here's Hollinger's take. The biggest difference with KG being out is the loss on defense:
ESPN's John Hollinger discusses Powe's potential as Garnett's backup
Quote:
Additionally, there's another positive that's gone under the radar. While Garnett has missed the past month, so has his backup, Leon Powe. Powe returned to the lineup Wednesday night and had 18 points and 13 boards in a win over Washington, providing a good indication that he'll be ready to deliver in the playoffs.
In every respect but one, the difference between Powe and Garnett is less than you might think. Powe averages 17.5 points and 11.2 boards per 40 minutes, and shoots 52.4 percent; for Garnett those numbers are 20.3 and 10.9, and he shoots 53.1 percent. Additionally, Powe draws fouls by the bushel, while Garnett rarely gets to the stripe.
The major difference between the two is on defense. Garnett is among the best defenders in the league, of course, winning Defensive Player of the Year honors last season. Powe competes and takes lots of charges, but otherwise is average at best. Powe also averages a foul every 6.4 minutes, making it tough for him to get extended minutes.
Plus-minus numbers tell a similar story. On the season, Boston's adjusted plus-minus with Garnett was +5.87 points per 48 minutes; with Powe it was +2.79.
If you accept that there's about a 3-point difference between Garnett and Powe -- which both the plus-minus and per-minute scoring numbers seem to indicate -- then it's still a big deal for Boston. Three points per game is huge, and the real difference may be large: Powe's foul-proneness makes him unlikely to soak up 40 minutes a game in Garnett's absence, and the other subs aren't nearly as good.
For instance, if the distribution of Garnett's 40 minutes becomes more like 24 minutes of Powe and 16 minutes of Glen Davis (-6.40), then we're talking about nearly a seven-point difference between the Celtics with a healthy Garnett and the Celtics now.
