Real Football (not Gridiron).

You have to be a freakin Spartan when it comes to Stamina.
There's a reason why top trained players falls over and dies of heart attack.

Also let's not forget all the dangerous elbows causing fatal blows to the head. All the slide tackles and lack of protection. In football you have to be so aware of everything going on around you if you're gonna have a chance not getting hurt or wounded. It's a demanding sport requiring lots of technique and training. As is Rugby.
