Rugby* for me followed closely by American Football. I’ll watch cricket, mainly the highlights though. I’ve watched Canadian Football and don’t mind it, bit too pass pass pass for my liking though. As a European I can shock ye all by saying I hate soccer. And as an Irishman I’m required to say, what about Hurling and Gaelic Football? Not that I would have voted for either.
*Rugby Union btw
I simply can’t understand why anyone would say they “like” watching American football. All I see during the few times I flip over to catch the score is beer ads, car ads, insurance ads, shots of the cheerleaders, shots of the crowd, shots of the blimp, shots from the blimp, and shots of the sidelines. Sometimes I actually see a replay. Not once while channel surfing have I ever accidentally come across a football game.
I like golf too, but baseball is number one.
Another vote for rugby (union).
I was going to mention the noble sport of shinty, but probably wouldn’t have voted for it either! 
Football (soccer) is number one for me both on television and live.
Dodgeball on The Ocho.
