Call BS all you want, but I'm guessing you left my high school in the 80's. I don't know where you're getting that 200 record stuff because I've never heard of it. Nor does it really make sense for you to bring it up because 1) we're not talking about the 200 2) very few male soccer players run track, and 3) the ones that do rarely take it seriously. I can remember three soccer players on the outdoor team during my tenure.
But, I used to run with the soccer players all the time on 3-4 mile runs and they would run fast. They could easily keep up with me. Two guys on the 4x800 team I was on that broke the District record were soccer players that fall. One of those guys turned out to be an All-American middle distance runner in college (DIII), but I'm guessing you don't know who that is. There have also been quite a few girls to make the transition from soccer to track/xc and they did exceptionally well.
And I don't know why I would lie about my brother's time trial time, or why you would call BS. If you need more evidence, I paced him to a 5:26 in the summer before his sophomore year in high school, the next mile run he did was at the soccer tryout his freshman year of college. His splits were really weird b/c soccer players don't have much of a sense of pace. So the conventional wisdom would be that he could have run a lot faster with an evenly paced race.
Soccer players have a strong aerobic base, I don't see why it should come as a shock that a professional midfielder with a small frame like Adu's could bang out 6 minute miles in training. Nor do I get that tired when I play 90 minutes of soccer on the weekend.
