Tbh Bonz US football gained it legs in the 20's and 30's here with college, Knut Rockne and Notre Dame led the way with their winning traditions, pro ball here didn't get its start till the 50's here then came to life in the 60's, peaking with the 69 super bowl.
Its a spectacle sport much like what the Romans did in the coliseum!
You ever get to the states and Florida I will take you to a Florida game, talk about a spectacle! and usually a good game !
Any way its a good excuse to blow some money and get drunk!
