I was thinking about this earlier as I was reading a bunch of NBA columns. I've generally just said that the NFL, MLB, and NBA are basically in a 3 way tie for my favorite, but now I think I'd have to put the NBA #1. I know I'm an outlier on this board in that respect, but am curious how the sports stack up in popularity on here. If you want to list soccer, try to pick a league instead of just generic soccer. Also, if you want to list non sports such as NASCAR, go right ahead.
Anyway, my rankings of all the sports I care about a fair amount:
1. NBA
2. NFL
3. MLB
4. UFC
5. College Hoops
6. College Football
7. Tennis
