Sixers coach Doug Collins was talking about how Kwame Brown's various ailments have limited the big man from receiving much in the way of productive playing time this season.

"He gives us a strength and a tenacity and a size in (the post) that we need," Collins said Monday after practice at the Philadelphia College of Osteopathic Medicine. "The big thing with him is he hasn't been healthy. It's either a calf muscle or it's an ankle tweak or a sinus infection. The one thing about the league is being able to consistently be out there."

Then a booming dunk echoed through the Sixers' practice facility.

It was delivered by Andrew Bynum.

The 7-foot, 300-pound former all-star center has yet to join his teammates in practice, but said Monday he intends to make his Sixers debut "right after the all-star break, in my mind." Sixers general manager Tony DiLeo has said Bynum could join practice as soon as the first week of February.
