I think if we were to move Smoove at the 3 & Al to the 4, the best team to model ourselves after would be Utah. All we would need a is a center similar to Okur. we somewhat mirror each other already.
???/Okur
Horford
Smith> ak47
JJ> Harpring
Childress= Brewer
Bibby
Zaza=JCollins
We would also need shooters off the bench (they have Korver & CJ Miles & Almond...we have (J Rich & Salim) and another servicable big ala Millsap. Horford would have to develop his inside game more.
A new coach would be nice too.
Marvin, doesn't fit in this scheme at all right now. But If he can get some range on his shot, he would be one of those shooters off the bench. As far as trading him, I don't know where to, I doubt Seattle would do it since they have Durant & Green.
