No, the idea that the U.S. 1500 runners should run the 10000 is somewhat analagous to asserting that 400 runners should move up to the 800.
No, it isn't. Not at all. The 400 and 800 are completely different events. The number of people who have competed well at both can be counted on one hand with a couple of fingers left over.

This is where we disagree. Most U.S. runners hit a certain level of success and stop seeking more. Look at Ryan Hall. He ran a great 5,000 at nationals (13:1x, as I recall) right out of college, and MOST U.S. runners would have stopped there. He didn't, and with much more dramatic results. This is the crux of the disagreement between you and malmo and the OP and the Grimes article as I understand it. MOST U.S. runners after laying down a sub-13:20 time would have believed that was their event and stopped there. Hall didn't. He looked at the trend of him getting better as the distance increased and took that to the next level. And, wow, what a level he took it to.
Think for a moment what would have happened if Hall would have decided to stay at 5,000 based on the results of his last year in college. Not near what he's done at the half-marathon and marathon, is it?
There is little/no similarity between the 400 and 800. But "distance running" covers the range from the mile to the marathon. A lot of milers put in mileage comparable to some 10,000/marathon types, but they stick to racing the 1500/5000. Why? Look at Alan Webb, a guy who can make a U.S. World Cross team at 12K and run a top-ten all-time U.S. list 10,000 while preparing for the 1500.
The similarities between events from 1500 up has nothing to do with the goofy-assed 400/800 comparisons. Chris (and you, too, malmo) I really appreciate your knowledge and what you have done for the sport, but I think you miss the mark here. The 400 and 800 have very little in common compared to the 1500 and 10,000. 1500 guys and 10,000 guys train together all the time for much of the year.
The problem we have is that the data sample of people who really stretch to reach levels at longer distances is very small, but that really small sample supports the OP and the Grimes article. Ryan Hall. Kara Goucher. Even Alan Webb. All started as primarily milers (Webb still is) and reached way above in distance and had great success. There are no (or at least very few) comparable examples for 400/800. One has to wonder what Lopez Lomong could do at 5,000. What could Lagat do at 10,000?
Why not try? Teg at 10,000 is really tantalizing. Fifth at World Junior Cross, 3:34 1500 and 13:04 5,000. Granted he needs to stay healthy enough to put in the volume, but the trend is clearly there.
The preparation for many guys between 1500 and 10,000 isn't that different for most of the year. If you're a 1500 guy who has run solid 3000's or 5,000's, why not try the 10,000?
