I think Danny wouldn't hesitate to make that deal, with or without promise from Kyrie. That is still a very strong team, one that could compete for a championship next season.
More importantly, I see Wyc co-signing to that deal. He often mentions the need to win championships, and to stay ahead of the Lakers in the ring count. If we are bidding against the Lakers to get AD, I see Wyc signing off on this trade.
