He plays atrocious defense.
Hopefully some GM out there gets enamored with Sully's offensive #'s and trades us a REAL big man.
I loathe undersized, slow-footed, no-defense, all-offense PFs. UGH!
Powe/Baby we're both pretty bad their first few years. (Powe never really got to playing good defense) But both figured it out with time how to play effectively, as has Bass.
Giving up on a useful big man 15 games into his rookie season because he's bad defensivelY? Most rookies are really bad defensively.
Well, if Sully does, in time, learn to play better defense, my opinion of him would likely change. I just don't think he will ever be a good defender. His atheletic limitations will likely always hinder him on that end of the court.
Unlike Davis, Sully has very little lateral quickness. Neither have any "hops", but Davis is a good defender due to said lateral quickness, combined with his gerth. Sully has some gerth, and a much higher IQ, but I really believe his lack of quickness will be the ultimate deciding factor.
As to your point about giving up on a rookie, I don't really see how getting a higher quality big man through trade, especially when we are in win-now mode, is truly giving up. Sometimes the best use of assets isn't keeping them and seeing them fully develop, it's flipping them for a better player in the here and now.
