Thanks for the input on the Grizzlies style. I figured they ran an OKC/Westbrook type system where their guards get the ball and move while their bigs box out.
As far as "we", I mean Suns fans. That's the modern NBA. The aversion to Ayton shooting 3's is he was a poor shooter from further out. He was a post player who couldn't post anyone up. If he could shoot 40% from 3, who wouldn't want him shooting from outside? He was supposed to challenge Embiid as the best modern Center in the league. Capable of doing anything. His 3pt shooting wasn't a requirement but if he proved capable of hitting them then it would have freed up the offense that much more. He wanted to shoot them but never improved. He sulked because Monty wouldn't indulge him despite not actually proving to be a capable shooter when given the chance.
It wasn't a requirement but he was supposed to be a top talent, a franchise C to lead us through this decade. What C in the league can be called a franchise C who isn't a 3 point threat? Wemby, Embiid, KAT, Jokic, Anthony Davis all fit that bill.
