Football players ain't fit mate, not even close compared to other sports. I remember Dacks come back, I remember screaming it was clearly to much as I didn't think he looked fit, more enthusiasm than anything else and was calling for him to do less pitch time. No he isn't a natural athlete, but very very few people are. You don't get a athletes body by not working it, even those genetically disposed that way MUST train hard. Stiffness and soreness sums football up, recovery is the main fitness focus and that means they are not fit enough for their sport and football is not physically demanding in the grand scheme of things. 90 mins main activity is walking with intermittent bursts of high intensity activity, Christ a tennis match is more physically demanding and that's scientific fact.
