I don't blame KD for not wanting to return to GS.
He's already been there and done that plus the Warriors don't have a team good enough to compete for a championship, shyt they'd be no better than where the Suns are at the moment, so returning to play with Steph would just be a legacy act for all the fans who want to see them for one last hurrah.
The truth is that the only way Steph will ever have another shot at competing for a championship is if he leaves Golden State, but I doubt he'll ever do that, so he's going to be playing the last bit of his career fighting for a Play-In/Playoff spot.
He's in a similar situation as LeBron before the AD-Luka trade, where we knew the Lakers weren't anywhere close to winning a chip, so Bron would be basically playing for nothing, as in a 1st or 2nd round exit to add to his Postseason resume. That's where Curry is at with Golden State, virtually playing for nothing more than a Postseason berth.
