I'm kinda hesitating on the Simmons though. Him at SF may affect his price. Especially with a lot of people using his other cards at PG, he may not sell for much.
1.) This is a tough one. Gary Payton already has a couple of Platinum cards, but he'll probably be more profitable because I don't think people would want to give up their Mutombos and maxed Howards for Gobert unless he's the best NBA Center in the game right now.
2.) SImmons obviously. C'mon, it's Ben Simmons. Okafor has some nice stats in key positions, though.
3.) I can't really say, but judging from a fan favorite perspective, I'd think people would pay more for Crawford than Lou. It would also depend on which lineup they need a better SG for.
