Celtics did it with Perkins who is far from dominant.
During their 2008 Playoffs when Boston won the crown, Perkins averaged 12 rebounds, 12 points, 3 block shots in almost 40 minutes per game. Pretty good numbers if you ask me. Especially when you play with the Big 3.
Perkins IS a force. That's why OKC got him, in preparation for the playoffs again.
On the other hand, who has Miami got aside from Z? The other big men are Dampier, Magloire & Joel Anthony. Bosh is a PF. Well, you can always say they also have a big 3 but then again, butas pa rin ang gitna.
