And rugby, rugby league, Aussie rules etc are essentially aerobic physical contact sports not anaerobic impact sports. These sports have relatively few stops, and certainly no time for advertisements outside of the half or quarter time breaks. And there are no bulky pads and helmets, and the physicality is just as dynamic, if not more, than US football. Cricket is like baseball, where it tends to be on in the background and you pay attention at each delivery/pitch. Cricket can last 5 days though... As an outsider in the US I was struck by the crazy high percentage of time dedicated to advertisements - even to the extent of intentional breaks for that purpose.
