That squad isn't too bad, you have a lot of quality players, but you might want to try moving a couple to even out your squad.
You have a nice group of swing-men, but you're going to miss out on assists, blocks, and rebounds if you keep that current team.
Butler, Granger, and Wallace are three very good commodities, i imagine that if you moved just one of those guys you could get good value in return.
The type of trade i'd shoot for is maybe moving Wallace for a package consisting of a true point guard and a defensive center.
