OK dude first of all I think we can do without the personal attacks...
So, you're saying that the NBA is "better" now because it has more athleticism? Who gives a shit about athleticism. Stromile Swift is perhaps the most athletic player in the league, what's he done? I'd take a player with good fundamentals and defense (ie Peja, Nash, Duncan, Ray Allen, etc) over an athletic freak (ie the ten billion players that jump from high school straight to the pros) any day.
Your point about the NBA having more black people is correct...however, I fail to see how it proves that the NBA today is better than the NBA of old.
Better coachers and more knowledge of the game? RIIIIIGHT. You think Steve Francis has the same "knowledge of the game" as Rick Barry? You think T-Mac has the same "knowldege of the game" as Larry Bird? You're kidding yourself.
