To keep it to normal sports, lets say only ball sports can be included. What do you think is the most boring? For me its: NFL/Gridiron - Stoppage after Stoppage after Stoppage. Most of the players don't even need a high level of fitness.
I agree with you regarding the NFL...fitness level is disgusting for the most part these days and the stoppage after stoppage is for the birds, BUT, I still do watch it when my favorite NFL team plays; they're out now so will not watch it until next year, lol. ...Tennis and Golf are the most borning to watch, I find, even though I do enjoy playing tennis.
You have to be fit to play in the NFL just like in any professional sport these days but constant flags and stoppages take a lot away from the game.
i don't ever remembering seeing a ball in ski jumping. I think baseball is a very boring sport. not much fitness needed to run bases. I do give props for people who can hit those 100+mph balls though
Given a choice between watching paint dry or Cricket and golf I would go for the paint everytime. Even watching grass grow is far more enjoyable.
