Is this a good Fantasy Basketball Team? Do I need to make any major changes.. (I Think I do)..?

If it ain't broken, don't fix it. You're in second place right now in a 16 team league. Pulling off a blockbuster trade may be too risky right now, even if all you want is a big scorer. If you really want to pull off a trade, though, I'd go for Smith and Jefferson for Stephen Jackson.
