I think Big Al is exactly the sort of player that this team needs. People malign him for his defense, but his inside scoring and rebounding ability is exactly what this team is missing.
Unfortunately, I'm not sure Utah is willing to just give up on him. He's still a 20-10 guy after all, and everybody has seen this post-season that it's a bad idea to undervalue a solid 20-10 guy just because he's always been on bad teams and can't play defense.
I've also read that Paul Millsap is going to try to spend time at SF, which would allow them to play him alongside Favors and Big Al.
Still, if it were somehow possible to do some sort of sign and trade deal with Green and Krstic for Big Al, possibly working it into a deal with NO that also sends out Rondo and gets us Chris Paul and Carl Landry, I think the Celtics would instantly become the best team in the East again.
Ah, if only such dreams could come true.
