I think the defensive question is key. Maggette is a heck of a scorer and could be really valuable if Allen or Pierce goes down or as Allen's skills decline over the next few years. I just wonder how valuable he's going to be next year. I mean it was a lot for Allen, Pierce, and Garnet to sacrifice stats for the greater good. Now you're asking for that to arguably be sacrificed more with Maggette coming in, plus you're asking Maggette to give up starting, stats, and money?
Plus, while I'd take Maggette over Posey if I was starting a team from scratch, I think Posey fits in better not only defensively, but offensively too. Think about Gary Payton when he was on the Lakers. Because the point guard in the Lakers system was basically a spot up shooter, Payton's many skills were for naught and the Lakers were better with Derek Fisher playing the 1. Same thing here. What are we going to ask Maggette to do on offense? He's not going to get that many plays called for him when he's on the court with two of the Big Three. And he's going to have to play with them a lot of he's going to get any minutes. People forget that one of the reasons Ray fit in so well was because he was a great spot up shooter. Even when the C's were playing the 2 man game with Pierce and Garnet, Allen was always a dangerous weapon as a deadly weakside shooter. Can Maggette actually fit in that role and be successful? I'm doubtful.
Posey can though, he's already done it. And he's fine sitting on the perimeter, spreading the floor, and knocking down open threes.
It's great Maggette can do more than that, I just don't think those skills are going to be what the Celtics need of him.
And it's great that he might look better 3 years from now. However, who knows where the C's will be in a couple years? For all we know, KG blows out his ACL and things go to hell. So what difference will it make if we have Corey Maggette? He's not going to guide the C's to a title.
Winning now needs to be paramount. History has spoiled us into thinking that championships are commonplace. However, this window might not open again for a while. Ainge can do his best to rebuild, but it won't matter if a guy like LeBron gets paired with another All Star or two in a couple years.
