I always loved Delonte in Boston - just a hard nosed kid, seemed like a Celtic and was one of my favorite players.
However, we've signed Barbosa and I think He'll add just as much if not more than Delonte can.
Also, even though he's young, I like what I've seen of Joseph and like having a 3rd option behind Pierce and Jeff Green.
Also, if I was going to cut Jospeh, it would be to add someone like Pietrus for more depth at the 3. Still, I think I'd rather have Joseph, I think he has some decent long term potential.
