Center - Jock Landale
Jakob Poeltl is one of my favorite Spurs, which I know may be a hot take, but if I were seven feet tall I’d be just like Jak. I’m a bit clumsy, can’t dunk, shoot free throws, or dribble in traffic. I can get in people’s way, and Poeltl has carved a name for himself as one of the best defenders in the league because he just doesn’t let people past him easily.
In this lineup, though, that’s not what we’re looking for. Jock Landale can spread the floor, dribble, post up, and has a similarly high defensive IQ. His shooting ability is undeniably head and shoulders above Poeltl's, and he can therefore draw defenders out of the paint on offense.
Unlike Jak, Landale will be allowing his teammates to get their own easy buckets or make plays for others while he draws out rim-protectors into midrange territory. And if Landale gets the ball himself, he can back down opponents.
Poeltl is certainly the better rim protector, but Landale is adequate and also has the ability to switch onto smaller guards due to his lateral quickness. Putting Landale in prevents any mismatches and rounds out the team on both ends of the court.
