The trouble with the Gridiron game is that every time it gets going it stops! If you get what I mean. Watching it is interminable. Games go on for too long. The action only happens in brief bursts and its all geared to advertising and commercial breaks. Many years ago I got taken to see the Patriots play in Boston. It was certainly an experience but In truth I enjoyed it about as much as I enjoy our cricket. Ie not a lot. Its only saving grace is its very tactical and stuff but so is Chess and that makes rubbish spectating too!
Football is 90 mins of non stop action, its tactical, full of larger than life characters totaly intense especialy when part of the crowd at your teams big matches ( sadly too few with Ipswich these days! ) and a great game to play watch and be part of. You can go for a couple of hours yell your head off and then go down the pub and speculate about what might have been. Roll on the real World Cup competition.
The downside is that Big money men who give sod all about the game are taking it over to milk for profit. Malcom Glazier anyone? And the players salary's are obscene! Still I'd take football over gridiron any day.
