In that sense, Jermaine O'neal's performance last night is a strong statement in favor of the argument that the Celtics didn't make such a big mistake trading Perkins after all.
The counterpoint to this is that there was plenty of room for both JO and Perk. It's not like JO played 48 minutes last night.
I don't know how good a counterpoint it is. I don't ever recall Perkins blocking that many shots on fast, athletic players quite like Jermaine did last night, and has proven he can do on a consistent basis throughout his career. I also don't recall Perkins being as versatile offensively to drop the kinds of shots that Jermaine dropped for the Celtics last night.
Perkins is not as quick on his feet or as offensively gifted, especially when he needs to do so with the ball in his hands. Some of the shots Jermaine made last night, would be significantly difficult for Perkins to make. In fact, with Perk, those same offensive opportunities may not have occurred, forcing the points to have to come from somewhere else, unless Perk was really deep in the paint.
The problem with that, though, is that even when Perkins was deep in the paint this season, he, a lot of times, blew amazing passes that went right to him, and no defender was close enough to stop him, and he still couldn't get the ball in. He goes up way too weak a lot of times. I've seen it myself this season.
So, I'm not on board with same perk did everything bad, not at all, but he was doing quite a bit bad, but the Celtics simply weren't paying for it as much as they could have, due to incredible play from elsewhere. Jermaine O'neal makes the Celtics more dangerous than Perk did. Same is also true for Shaq.
