I never said that individual football players don't demonstrate skill. What I am saying, is that each football play is basically a pre-choreographed, memorized "route". Therefore, it is questionable whether football should be considered a "sport" the same way that hockey is.
Whether someone like Barry Sanders found a very successful role within that framework is beside the point. And if his coach had hated him for some reason and refused to get him the ball, then yes he would have had less success.
Even though I was a much better football player than a hockey player, and absolutely loved the game of football, I too prefer hockey.
Nobody is going to argue with you: everyone knows football is a lot of planning, plays , formations, and schemes on both sides of the ball, vs the very high degree of randomness that takes place in hockey.
Of course players have to know the plays.
But ultimately, the players have to execute. That's called "sport".
They have to be able to "sport" (execute) once the ball is snapped and all hell breaks lose into mass mayhem on the field, as some of the biggest, strongest, fastest, most athletic men on the face of the Earth try to impose their will on you.
How you seriously cannot see the sport in that is beyond me. You're either dramatically short sighted and ignorant, or a pretty relentless troll.
