How does NASL's attendance stack up against 2nd Divisions world wide?

Earlier today I was perusing my Twitter timeline and saw a very interesting graph from Mike Pendleton about NASL's attendance. I had actually never thought of asking this question before... you see NASL vs MLS vs D1's in other countries but I had never even thought of looking to see how NASL stacked up vs some of the top D2's in the world.

It is interesting to think of the US having a stronger D2 than Mexico and basically equal to France attendance wise and not too far behind Italy and Spain.

Every day if you follow the Open Pyramid discussion on social media you will see the argument made that "we just aren't ready" and that our D2 "Isn't strong enough yet". Well according to this metric we are just as ready as some of the greatest soccer nations in the world.

I would love to hear your opinion in the comments or by using the #ProRelForUSA hashtag on Twitter and Facebook.
