to finish your title...
nobody who will make us any better.
until wiggins is playing in another pro uniform, getting him would be my sole focus.
Guys like dwight and smith are always exciting, but i prefer to dream about somehow getting the younger guys that seem poised to have a breakout soon- like hibbert and aldridge did in recent years. Still very good players, but not quite on the same tier as howard. I dont know who those next guys will be, but they seem like the best choices. Off the top of my head maybe larry sanders, jason thompson, thad young, or one of the morris twins?
I like all of the players listed above, but most of them will get max salary in the near future. I would rather go after players who aren't at that point yet, like J.J. Hickson was two years ago.
