Fitness
Differs with the demand. And AFL requires a higher cardio fitness whereas NFL/CFL seems to require ground to opponent strength. Short bursts of power.
I'd say that Soccer would also require a high cardio fotness as well. But seeing the players, they are hardly as built in the upper body, so perhaps the cardio demand is even higher.
Rugby and the NFL/CFL really are similar in their physical demands, as there are many stop/starts, but they throw the ball backward so it takes much longer to get the ball across the line.
I never was very good at sports, but I was unfit as a kid so it never suited me. Now, however, my fitness has increased somewhat, so I may enjoy it a little more.
Haha, I could imagine the difficulty in the NFL/CFL players trying to get their heads around the need to bounce the ball whilst moving!
