Soccer may be the world's most popular sport but it has a bunch of catching up to do in America. The professional and college versions are way too defensive and boring. My kids and their friends all played soccer when they were younger. A few made it in high school. Today, with most of them in their 30's not a single one follows or plays soccer. In contrast, more than a few of them still play hockey as adults.
The Olympics as broadcast by American networks likewise. The endless commentary and fluff segments take away from the actual sporting events and the broadcast times are a problem in most years. I quit watching years ago. Could not stay awake.
And, after a lifetime of playing and watching football, the NFL is out of luck with me. I still watch the college game but the pro's are just too predictable and boring to spend time with.
Baseball? Ha! Ranks right up there with golf and tennis. Although I played a ton during my youth it is way too slow these days. Golf and tennis were non-starters.
