Ainge isn’t doing that. There has to be at least the appearance of future-facing talent value (or just general talent upgrade) for him to do it.Because Lyles and Huerter give you less wins than John Collins. Lyles expires this year and Huerter's expiring is an easier trade than Collins expiring. Shooters always have some sort of value.
I’m also not that convinced that Collins actually helps the Jazz win games so I’m not in a rush to trade him. Kessler is much more of an anti-tank, Collins is kind of stealth-tanky. That dynamic matters because Collins pushes Kessler off the floor (or forces a three-big lineup).
