Thats the whole point, if LeBron was born in 1938. they would have forced him to play center because 6-8 dudes can't be guards ever and he'd probably be skinnier and they'd tell him that lifting weights is bad and smoking cigarettes is cool, that's why you can't definitively say today's guys would be better, unless they invent time travel.Generally, this is true. Watch old NBA games and its really cringey. Honestly, it looks worse than current NCAA. Players have gotten better, mainly because of training advances. If the other eras trained the way these players do from age 6 up, they would have been just as good but they didnt so they are considerably worse.
