I'm not a fan of Amir Johnson, and I'm not convinced that Travis Outlaw is going to be somebody we can count on.
For free agent small forwards, I like Mike Miller. The guy can play three positions, he can shoot, he can pass, he rebounds, and he plays defense.
Carlos Delfino would be another good SG/SF for us, if Milwaukee doesn't pick up his contract (which I think they will).
Rasual Butler would look great in green, as well. Kyle Korver would be a good fit, as well.
