As I said at the time, posturing. Jordan isn't getting an All-Star in return and he knows it.
Walker is the one with the leverage here, because he can walk for nothing in just over a year. They obviously can't afford for that to happen, so a decision needs to be made this summer if they want to maximize value.
He's clearly not interested in re-building and is probably only interested in status quo, if they offer him a Conley or Holiday type contract, which wouldn't make sense on their part.
Neither team does that. Hornets because Leonard would obviously not re-sign in a year and Spurs because Walker really only makes sense as an addition to a Leonard centric team.
If Leonard forced a trade, young players, prospects and picks are what they should and more than likely would be after.
