I gave the hypothetical to my friends that if you were given 1000 years to train to play LeBron in a 1v1 (time is frozen while you train), would you beat him? In my opinion this is obvious you still stand no chance, but my friends are adamant that you would win.
Realistically, for the average person? No. You can train all you want, but at some point you are going to max out, and the size disadvantage will probably doom you. Even if you could hypothetically train to the point of being a knockdown 50% shooter from 30 feet out, you’d score on him but would still have the fundamental problem of trying to stop Lebron with your 5’10 body.
Now, if you were 6’8? Then yeah, if you had 1000 years to build up muscle and train in basketball, you should be a pretty fucking good player. At least good enough to give Lebron a fight.
