The TLDR is I think Aaron Gordon could be The Piece. I think he has another jump in him.
He'd have jack **** to play for for the first time, in addition to the the best development staff, teammates, culture, coach, and fans in the league. He'd be the jack-of-all trades and de facto 2nd option on a team that he could provide spacing for and can reciprocally provide spacing for him as he'd nominally be the 4, but playing alongside one to two others that can seamlessly switch. He'd seamlessly fit into the culture and the philosophy from day one.
Even if he didn't develop much further, his athleticism would amplify the terror that this team brings wherever it goes.
I don't know what it would take, but I somehow feel like this is in the realm of possibility.
