Well I’ll go against the grain.
I can identify with soccer. I can’t identify with concussions or jumping 40 inches.
As for watch-ability, I’ll take 90 minutes (call it two hours with extensions) over three hours.
Plus there’s the thug factor. How many assaults should be allowed before a team becomes unwatchable.
There’s more concussions in soccer than football.
Concussions will bring the end to American football.
