Soccer players would win 800 and up. They would compete at 400 and 200 but wouldn't necessarily win every time. Some forwards have some incredible speed. Now of course there will be some outliers in every sport that can dominate each distance but the average soccer player would beat the average athlete at any distance 800 and up.
I agree with this. I just give basketball players a chance here, because I don't think they would have a chance anywhere else. But, yeah, middle distance on up, soccer players would rule.
