hah, I didn't notice that was nut... I was just about to say he was missing...
re: substitutions... That is a good point as well. Like you say, soccer only has 3... IIRC baseball is the only other major sport to have a limit (roster size, a player can only be entered to play once per game)...
Hockey, basketball, and football (although there are some complicated procedures for some positions) can sub in/out pretty much at will and as many times as they like. Hockey is the only sport where changes can be made on the fly, which is important as well.
Another interesting area to look at is penalties... hockey and soccer can become MUCH more strenuous when down a man--moreso in soccer because it is permanent.
where would golf rank?
