If we were to trade for AD, makes more sense to wait for a lot of reasons.
1. Wait until we have Hayward back to have a missing key piece to the roster to make a legitimate push against any team in the league.
2. The value of any trade chips we would likely include all seem to be trending upwards. Tatum is flirting with "untradeable" status. If he continues on his trajectory, wins ROY, it could get to a point where a player like Tatum would be almost enough to fetch any available superstar, IE Davis, without having to include mich more.
Brown is a little further behind "untradeable," and at the moment, speculative trade proposals are Tatum/Brown AND picks??? I would cringe to have to give up any two of Brown/Tatum/LA pick for AD. At this point in time a trade offer of Brown and LA pick is not enough for NO to say yes, but by the time the draft comes along, with some luck and actually locking in say the #4 pick to have an actual name attached to the pick, NO might have to consider this, knowing AD might eventually leave or request a trade. Then Tatum stays here.
