The players aren't bigger, stronger, faster, jump higher than the players in the 90's and 2000's. The style of play has changed, there's more guys who can handle the ball and shoot threes really well now and they're given far more room/leeway with crab dribbles, step backs, Euro steps, foul baiting etc. The game is a lot more spaced now and much more dependent on three point shooting and more analytically advanced but these guys don't have the post moves/bang in the paint that those guys did/finishing through contact and Jalen Duren and Zion Williamson are about the only guys who looks like they could hang physically with Karl Malone, Shaq, David Robinson, Barkley, Anthony Mason, Ben Wallace, Kevin Willis etc.
