Perk is a good center, and good fit. There aren't many centers who you could swap him with without the Celtics getting worse. He's an above average center so theirs nothing to complain about.
I'm a little late to the game on this one (man 5 pages deep, I'm definitely slacking) so I'm going to start off saying ManUp got it dead on with his statement.
I think alot of the people here are arguing two different things. Perk is not the most skilled center (I agree, and this is what I think the OP is saying). But most of those 15 guys mentioned, the C's would get worse (which I also agree with). Of those 15 Centers, who would play as well as Perk does as a 5th man? Sure if I was building a team, and only those 15 players were available to me with my first pick, I'd pick alot of them over Perk, but if I have 3 established All-Stars , and 1 emerging All-Star and need to fill the starting Center role, Perk would be one of my top choices.
I think it's just sounds ridiculous because the way the OP comes off. I can list a whole bunch of guards better than Eddie House, or I can list a whole bunch of PF/C's better than Sheed or Big Baby too, but trying to point out that a franchise cornerstone is much better than these players is pointless and unrealistic (because those kind of players aren't going to fill the role we need them to, or play for the salary we need them to, or is even attainable in the first place). It's not like we passed up any of those guys to get Perk. Most of those guys were top 10 picks, Perk was 27th, what's the point? Hey Chris Paul and Deron Williams are better than Rondo, why don't we start a thread saying that too?
For fun, who wants to look up and see how many Centers were taken before Perk in our very own CB draft?
