John - I kind of agree with you - In every sport, players have gotten stronger, faster, smarter, and overall more skilled.
I was watching the 1984 Open Championship tonight, and today's swings are so much better. Most of the players in '84 still had the "Noonan" reverse-C where today's golfers are chiseled with scientifically based swings.
Getting to John's basketball analogy, I'd like to compare women's basketball to where it was 50 years ago. 50 years ago, it was a 6-woman game with 3 players on each side of the division line (3 offense, 3 defense). Players could not cross that division line. Today, women's basketball is an Olympic sport (although it's time for them to use a regulation size golf ball).
