It depends on many factors. I was able to exit my D4 league for D3 with a 3.7k SG and a 5.3k SG playing PG. Obviously, the strength of D4 has probably heightened a little bit, and I had exceptional inside talent, but you should be able to compete with that guy, even as a starter. However, even so, you might want to get a little stronger guard, around the 4.5-6.5k range. However, if you see any good bargains on higher level guards, jump on them.
