Joe Johnson would be nice too. probably more realistic. basically, someone who provides some offense but isn't a liability on defense. you need solid defenders around Greivis.
I don't love Delfino as a starter. Other than that, it has ZBO, so it should probably play a grind it out halfcourt type of game. Asik and Manu won't mind but the rest of that roster would probably rather run. i'd prefer a Bosh / David Lee type on this team. But it's not a major thing. i like it, i don't see anything bad with it. it should be great offensively and above average on D. i don't know if it's among the most talented or not, i don't remember most teams. but it is well built.
that team would be a fan favorite. i'd look at trading for a major low post threat who can also defend very well. I don't know who that is. Duncan, but i won't trade him, Dwight, not sure if he's available.
