It's not a question of physical feats, it's a question of load, rest, and workout type. You're dismissing our arguments out of hand as ridiculous, which means there's no reaching you on this subject.
I don't know how you can imagine off-season workouts are more dangerous to players than in season games when the vast majority of injuries occur during the season. You can continue to post on this without any data or you can look it up.
I mean it's not hard to look this stuff up: "Data shows NBA injuries up in condensed season"

Not that I expect people to listen to or believe NBA players, their trainers or the science, of course!
