Although I have long been a fan of pro basketball and hockey, I have a distinct dislike for the extended seasons of these two “winter” sports into the month of June.
Seasons could be shortened, while keeping the number of games constant, if only these two sports would follow the game of baseball by adopting the two- and three-game series, the latter for intradivisional games. This would have the side benefits of reducing travel costs and player weariness over fairly long seasons.
Baseball could also reduce time and travel by ending the two-game series and expanding the number of four-game series, as Triple A baseball already does. Football, of course, is perfect.
