If Barbosa is traded for Felton, it'd pretty much be an admission that the "Goran Dragic is our pg of the future" talk over the past few days is bs.
I've thought a pretty fair trade in terms of talent and reasonable contract is Barbosa for Udonis Haslem. With Beasley (and Marion playing some pf) there's not much time for Haslem, but Miami does need bodies and shooters in the backcourt. If they were going to trade Haslem, Miami might be able to get a better fit than Barbosa (more of a point and defender, like Earl Watson), and then we'd need to find a cheap backup 2 somewhere, so maybe it wouldn't work.
