I've given up paying attention to US pro sports. I stopped watching TV in 2010, and watching sport on TV (indeed, watching TV in general) turned out to be easy to drop.
My big sport was hockey, which I quit playing just before the turn of the century. That led to watching less of the NHL, and a couple of player strikes resulting in cancelled seasons led to the realization that watching was not essential.
Baseball and US grid football are too time-consuming with little action. Games can easily take four hours with innumerable mind-numbing advertisements.
If I was to take up watching a sport it'd be big-time Euro football: continuous flow, no commercial interruptions, game over within two hours. But I lack the background and understanding of the sport.
