For me its got to be basketball, football, hockey, and then tennis. I love the NBA season and can watch basketball nonstop without getting bored because of the fast pace. Football is definitely a lot slower to me, but my friends are big into it so I've learned to enjoy it over the years. Hockey is similar in that I just like it because all my friends are big fans so we watch together. As for tennis, I used to play competitively when I was younger, so its entertaining to see how good the pros are compared to my highest level of play.
