Took me a while to decide what my least favorite is, and finally decided on basketball. By and large I consider baseball, basketball and hockey to all be about the same. Great to watch in person, but too many games to take any one seriously enough to watch on TV. One thing separates basketball, though. The best part of any sporting event is the end of a close game. Either the final 2 or 3 minutes or the last inning. Basketball has the potential to be the most thrilling of the sports due to the speed and athleticism, but they've actually found a way to make the whole thing painfully boring and tedious.
