Just to expand on that the NFL main competitors are probably the premier league, formula 1, IPL etc.
Afl is just a pimple on the ass in terms of world sport
Well that's what you get with a minnow population, yet still, it's averages are heady stuff.
We can all sit here all day arguing frivolous stats and how minnow the AFL is blah blah blah, at the end of the day it's still managed 4th highest avg across all competitions world wide. That's not up for debate, one can either acknowledge that or ignore it, won't change it though.
