If they went after Ant who's definitely NOT on Kyrie's timeline, why not just go for the traditional rebuild package like young players + picks? With Luka they are almost guarantee to have a shot at acquiring any great young talent maybe with the exception of Wemby. And IMO twolves is absolutely foolish to not take Luka for Ant. Ant's absolute ceiling might not be as good as the player that Luka is right now.
But I think this source isn't true cuz Nico said he only spoke with the Lakers and if the Bucks & wolves knew they were shopping Luka, it's unlikely for them to keep the whole thing a secret for this long.
