I'm loving this, really.
I thought Sully, and also Bradley, were assets to develop for future trades, but these kids are so different from Big Al, to name the biggest project before KG. These kids play D, not good D, but fierce D. They are both building blocks, you need this kind of players to start or come off the bench for your team, and they have the talent to (hopefully) be great players in this league. They can score right now, and they'll only improve in that area.
Now we just need, at least, a Big who can protect the rim and a wing scorer. Melo and Green could be those, but they have to prove it. Add Courtney Lee and a couple of quality role players, one at the wing and one big. Of course, Melo and Green could end not reaching their potential, but I think Danny needs to keep those players to take a chance on that team. Terry, Wilcox, Bass, are players to try to win now, while KG and the Captain are still playing. But that young core needs to stay in green.
Give Sully another month. He'll be even better.
