Some flawed logic on your part. They were still learning the game in 1932 and no one had grown up playing. Doesn't mean you can apply that to all of basketball history.
If Wilt Chamberlain was playing today he would dominate. Russell would also be terrific.
MJ is better than any player playing today, he could come back and crush. So, kind of depends.
But yeah Lebron could hold his own against these guys. Works both ways.
