If I am Denver I am not sure I want to trade quality core adjacent pieces (I don't want to call them depth pieces) for Durant who is probably going to be hurt or worn down once playoffs roll around. Their bench really hurt them in that series against the Twolves and I think you are right if they played that series again the Nuggets win it. They started the playoffs slow but were able to beat the Lakers despite not playing that well. Not so lucky against a good defensive team like Minny when they didn't show up in the first two games.

I don't think they need much improvement other than maybe some better bench options and knowing they aren't destined to be a dynasty, they have to earn it every single game.
