I imagine Charlotte was holding out for one of the Brooklyn picks.
I would have offered #16, BRK's 2016 pick, and Bradley.
Lots of people around here placing a lot of hopes on those BRK picks, but in a weak East it's always more likely a pick will end up in the middle than at the top or bottom of the draft. This draft had a strong top 10 and was very weak everywhere else, so paying a premium for a pick in that range made sense.
Having all of these first round picks has diminishing returns. We only have so much roster space for role players on rookie deals. Other teams know that, which is why they're going to try and squeeze Danny for multiple picks in every deal.
