And the number of defenders between the ball and attacker, and when the goalkeeper counts as one, etc.
Or none if they're behind the ball. Also what body parts count as offside. Also that it doesn't apply in the defensive half.You mean there needs to be at least 2 players between the player and the goal. Not really that complex is it.
Not easy to cut it down to three, but most forms of Motorsport are up there - and F1 used to be above football for a while but that's drifted off now.
Snooker I'll also watch happily, and have seen an O'Sullivan 147 in person with the only game I'll probably ever attend - if you watch back the 2007 UK Semi-Final, the person in the Wolves top is me (you can see me when he goes down for the last blue ball https://www.youtube.com/watch?v=7iRZFJsErqw)
And triathlon I'm a big fan of as well. But I could list another 10 sports and on a given day they could all be favourites behind Motorsports and Football.
Surely the only blue ball for a 147?
Cricket
Darts
Snooker
Just gone with what I spend most of my non-football time watching because determining preference will take forever and change day by day. There aren't many relatively mainstream (so taking out equestrian, water polo, speedway, netball etc) sports that I don't watch. Never had any interest in horse racing, cycling isn't for me even though I understand the appeal and I don't like rugby league. Oh and NFL, I've tried, not my bag I'm afraid. But I do like baseball and ice hockey.
I'm not sure I'll ever determine if I like football or cricket more. Fortunately it isn't a competition.
