You're correct about pick quality over quantity, of course. But the timing of the picks and their protections are critical as well and I think this is where Utah won that trade.
Rudy is 30. At the end of next season, he will be 31. As much of a freak as Rudy is, I don't see his game aging well when his athleticism starts to slip and there isn't much he can contribute elsewhere beyond defense so that his contract doesn't become an albatross. Unless he signs an extension, KAT is going to be a FA in '24. Also, as we've seen with Brooklyn, team chemistry is a fickle thing and Houston now looks like their goose just **** Fort Knox. Ant is only horse really on that team with a measure of control and relative certainty, but I don't think he can carry a team by himself. Let's also not forget the Wolves are just, in general, a historically bad franchise.
Aside from the quantity that Ainge got, there is a certain probability that more than one of those picks will hit. If so, good for us. In that sense, the quality is there.
Regarding Don, I agree. A lottery team would be better for us, but let's see how it plays out.
