You guys don't understand Kenyan racing. His ability is not nine minutes worse just because he blew up to a 2:11.
Say you run a 14:30 PR. You then have year of bad training, interruptions by injury, whatever. You believe you're in 16:00 shape. The average American runner in this position will go race a 16:00, running to their ability that day, if not going slower and making excuses, "tempoing it" rather than being seen running flat-out for a slow time. A Kenyan will race to WIN no matter what, even if that means running 14:00 pace to start then crawling in with a 17.
Kimetto is probably in 2:05-2:06 shape and could have even-paced that to some minor placing. That is what Hall would have done. But he ran 2:02 pace with the leaders, leading to a blow-up and 2:11.
