I agree with all of this, of course Green has benefited greatly from learning and developing in the best system in the NBA, with the best coach of all-time and a top 5 player of all-time, tbh..
My point is simply that Green's skills(shooting and playing defense) would translate to any good team in the NBA, we have seen it for ages in the NBA..the Spurs aren't the only team in the league that can create shots for role players, especially this year, where they had struggled to create shots for role players until this recent resurgence(Green was having a career year as the 3rd scoring option behind Manu and Duncan earlier in the year)..
I don't really understand the Neal comparisons, too..by any analytics you can use, Green is an elite perimeter defender..he's overshadowed by Kawhi, since KL is the best in the NBA(as Sean Elliott recently said), but he's nothing like Gary Neal, who was a massive defensive liability here(and is nowhere near the rebounder Green is, nor the team player)..
Their only similarity is their spot-up shooting..outside of that, by any measure you use, they aren't comparable..
