I've got nothing against POB, but there's several simple facts to keep in mind:
1) It took Perkins FIVE YEARS to be the serviceable center he is today. (I like Perk, but that's still all he is.) So don't expect C.Ray to perform miracles overnight.
2) #1 above is made worse by the fact that POB will not get much playing time, at least not right away. (This was also part of Perkins' problem early on.) He certainly is not ahead of Leon Powe in the big man rotation and probably not Glen Davis either. He might be used in very select situations like against taller centers (Z, Yao, etc.) but otherwise will ride the pine.
3) POB should have shown some potential by now. I applaud him for waking up to hard work, but I really don't see the necessary talent.
It's very possible that POB shows steady improvement as a Celtic and then becomes trade fodder down the road, just like Delonte West, Ryan Gomes, etc.
I'm not the captain of the POB fan club here, but lets be fair...POB hasn't played enough NBA minutes "show some potential by now." If you aren't on the court you can't make a judgement one way or the other.
What POB did show in the NBADL was very encouraging, particularly rebounding and blocks...so he's definately showed talent when and where he's gotten PT...
I don't think that Nellie-ball is unsuited for him though, he is just as mobile as Biedrins, so the idea that he didn't play because he didn't fit is untrue...more likely it is because Biedrins was getting the time as the primary center and Nellie wanted to use a different type of center off the bench...POB also wasn't as fundementally sound as Biedrins, so he got beat out for the one role requiring a player of that skill set...
But why didn't he get the minutes and Biedrins did? If he's just as mobile as Biedrins and would fit Nellie's style I would argue it's a simple matter of talent. Biedrins is just plain better. It's as simple as that. The same thing will occur in Boston, at least for this year. He won't beat out Powe and Davis for minutes. Look, I'm not against the move and POB could come around, start working hard, as surprise a few people. I sincerely hope that's the case. I just get the feeling that C.Ray is going to take this kid to a certain point, but his maximum upside might not even be quite as good as Kendrick Perkins. At that point, he becomes trade fodder, but even that is not such a bad thing. Danny's system of developing talent and then using those developed players to make a more significant move has worked out pretty well.
Oh, and I wouldn't read too much into his D-league showings.
I tried to make this point earlier. POB has a history of poor fundamentals, this has been evident since he was in college. The fact that he was near equal to Biedrins athletically was irrelevant when you factor in Biedrins had him beat coming and going with fundamental basketball skills such as footwork, passing, defense and a host of others.
This is the difference Clifford Ray makes and has made with Al Jefferson and Kendrick Perkins. Both certainly had talent coming into the league, but neither had good fundamentals or a solid foundation of knowledge to build upon when they entered the league. Clifford Ray was a big part of changing that.
As a side note, it has been mentioned widely on other blogs and in articles that in general Euro-foreign players have much better fundamentals coming into the league than many young NBA players, especially those that play little or no college basketball.
To be honest, most of the young one and done guys are drafted on shear potential and outstanding athleticism. It is almost never mentioned that one has exceptional basketball fundamentals.
