Good points.
The lack of competition thing doesn't really fly with me as there was a guy named Chamberlain playing then, along with Jerry West, Oscar Robertson, ELgin Baylor, etc. Plus there were only 8 teams so there was very little dilution of talent. The difference was that nobody had ever played like Russell or Wilt up to that time.
Jordan won six in a row (with time off for baseball) and there was certainly plenty of competition.
Once I scored a basket that still makes me laugh.
