Curry looks like a freshman yet has the highest deadlift on his team. He is in elite shape and probably covers more track than any other player in the league.
Klay had been an ironman up to this point and only had one season under 73 games played.
2 of them succumbed to freak injuries, not to mention that Steph and Klay have been through 5 straight Finals playoff runs which none of the Bulls did.
Scottie back was toast in '98 and Dennis missed over 15 games twice with the Bulls. MJ also missed an entire season because of a broken foot, same as KD.
As Kobe demonstrated, you can take excellent care of yourself to help stave off injuries but it really comes down to luck and genetics.
