I'd go with football as the clear #1... The NFL is huge.
Basketball is probably a close second, with an enormous following for college hoops... I don't think as many people watch the NBA as the NFL (at least during the regular season), though, probably due to the season's length.
Hockey and baseball are pretty far behind in popularity, I think, with golf and racing gaining ground.
For the record, my favorite to watch is college basketball, college football, and the NFL... I enjoy hockey as well to a lesser degree, and I hate watching baseball. I would love if soccer became bigger in the U.S. (I played most of my life).
