No worries Melvin. I've just become a bit of an NFL evangelist in recent times, so I feel compelled to stick up for the game when I read comments like that! :)
I actually used to think the same thing until I started to get into the NFL a few seasons back, and I still think that as far as sheer "toughness" goes, the players could definitely learn a thing or two from our AFL guys. Like someone else said though, we don't have 300+ pound gigantors trying to squash people in AFL. And I think on average, the momentum in many of the collisions can be very high, even higher than in the AFL, due to the nature of the game ie. that the burts of action are sporadic, and over short distances, and there's pretty much guaranteed to be someone running at you in exactly the opposite direction who wants to squash you. There's no running for 30m on an open paddock like in our game.

I think they're overdoing it a bit with "one of the best players in the history of the AFL"...
