Idk if it's a two bigs lineup since KAT is their best shooter.
KAT and Wemby would definitely work. That's why I want Markkanen. If it's to work, one of the bigs has to be an elite shooter, even for guard standards.
And the other one also has to be capable. Which Gobert obviously wasn't.
If we're talking about just finding a backup for Wemby, I wouldn't worry about it too much until we're actually a serious playoff team.
Until then, either get a young prospect or one of those veteran minimum guys.
