Coach Jillert Anema is talking about football, and he does have a point. If the US dropped football and had everyone instead focus on speed skating, I'm sure the US would be better at it than it is now. I don't think it's a stretch to think that someone like Denard Robinson, if he were a speed skater from childhood, would be quite good at that sport. .
"You have a lot of attention on a foolish sport like American football and you waste a lot of talent, athletic talent, on a sport that is meant to kill each other, to injure each other. ... You're so narrow-minded, and then you want to compete against the world [in other sports] when you waste a lot of time, good talent on a sport that sucks," he said.
OTOH, I doubt football linemen would have much success as speed skaters, and of course there's the whole thing about his claim that the most popular game in the US sucks. To each his own I suppose.
