Baseball is the most boring sport invented next to soccer.
As a 1970s era fan of the sport, I would venture to say there is no sport more boring than modern day NHL hockey.
Gone are the 11-7 shootouts, the near constant body checking into the boards, the fights and brawls breaking out. On top of that, almost nobody wore a helmet.
I remember one game in particular from the 1970s era in which I attended at Boston Gardren. The Bruins trailed 4-0 going into the third period and many of the businessmen with corporate tickets were heading to the exits to beat the traffic home. It was one of the craziest third periods I ever saw, the benches cleared several times for brawls, and the Bruins came away with a 7-6 victory.
That kind of game could never happen today because there is a zero tolerance rule on fighting. What used to be a five minute major penalty turned into a multi-game suspension.
Also, much of the thrill of the wide open play has been taken out of the game with the near constant dumping of the puck in the other zone (icing) and nearly every potentially spectacular play being whistled offsides. This forces the teams to adopt a very safe but paralyzing "neutral zone trap" style strategy where the players are mostly clutching each other between the blue lines, trying to keep the other team from making any kind of offensive play. This results in mostly 3-2 snorefests and a lot of ties, which recently have been resolved into shootouts but in those, the losing team still gets a point which is lame, lame, lame.
I never minded the slow and measured pace of a baseball game on the other hand. The constant pitching changes are a nuisance however. Teams should be restricted to just one pitching change a game - the starter and then the reliever. If the reliever gets injured, teams must be forced to bring somebody in from the field, such as the shortstop or left fielder.
