Just a couple of thoughts about America's favorite pastime (and mine)--Baseball.
1) If the Baseball Hall of Fame really is meant to enshrine the best major league players, then Pete Rose, Barry Bonds, Mark McGuire, and Roger Clemens (among others) belong there. If, on the other hand, the Hall is meant to happily thank above average players who have otherwise led pristine lives, then leave those named players out. While you're at it, however, you'll need to cleanse the Hall of some existing members for being something other than model citizens. Ty Cobb and Babe Ruth come immediately to mind.
2) What with just about every play being subject to video review, and machine called balls and strikes on the horizon, why not just eliminate all the field umpires? Perhaps one could be retained to make balk calls, but nothing else is really needed at this point.
3) The length of games is still an issue. The only solution that I can see is to change the number of innings per game from 9 to 7.
