PJ's big, but I don't see him doing much on the floor besides offer length (unless you count the offensive line move clearing space for PP). He played a lot of minutes tonight. How about more time for Powe? Grabbed a couple of tough defensive boards during his limited time and he finishes much better than PJ.
For some reason, PJ Brown gets away with more "clutching" fouls than anyone I've ever seen. He's allowed to hold people down with his arms from the front, the back, wherever. Watching an HD broadcast, I can see this clearly, so I'd expect the referees 5 feet away can too.
Don't get me wrong, I like PJ - but he's never been a scorer. He brings so many things to the table, but the uncanny ability to evade the whistle may be the most important.
