I would say that I love sports. Why would I only have one to choose from?
IMHO, there are certain sports that I like more than others but there are many variables when seeing a live sporting event.
I like watching hockey because it is very fast, skill level on ice, the hitting, etc.
I like watching a baseball game when there is a great pitching matchup, hitting. fielding plays, etc.
I like basketball when great players are playing one another (i.e. LBJ vs. Kobe).
I like football because of the many plays that can be run and guessing what the other team is going to do.
