Sully has a unique skillset, fills a key position on the court (it's all about the PF spot, IMO), is improving incredibly as a rookie and belongs out there already, has a low-allstar/6POY candidate ceiling and could get there very soon, and could complement any C and SF in style and substance due to his versatility and BBIQ. He can score and rebound. And he's a rookie on a rookie contract.
That's about it. Trading him for someone like Gortat would be, according to this upside-only take on him, a lateral move, especially if he's starting over Bass to start next season.
And that's a possiblity, which would have us look like a nice mix of talented youth and experience:
Rondo/Terry
Lee/Bradley
Pierce/Green
Sully/Bass
KG/Wilcox
If Sully comes around over the course of this season like he might be starting to, we're retty darn well set.
The only thing we could do is try to get bigger, and then only if we're not happy with giving any minutes at all to Collins.
In that case (wanting another C), we ship out Bass, Barbosa, Collins, and a pick. I actually would rather keep Joseph than a 1st rounder, and perhas Melo as well.
I dunno...does that sound nuts?
