Team's value the Foward positions higher than center it appears. On top of that Zion by many is still considered a potential generational player. Michael Porter Jr was also projected originally to be a Superstar. Ayton plays center has never been projected to be that level of a player. I am not saying that Zion or Porter JR. gets there either.Deandre Ayton is worth the max if Michael Porter Jr. and Zion Williamson are worth the max.
Just the reality of today's NBA.
