Jakob made a stacked field look mediocre in Eugene. I expected him to win, but not that easily. Sure it was slower, but then he won in Florence last year in 12:47 taking down the guys who would go on to win 5000 gold and silver 7 weeks later in Tokyo - both of whom are 26:30 or better guys. The energy systems used (anaerobic v aerobic balance) between the 5 and the 10 are very similar. I don't see someone being a 12:47 guy if not better and not breaking 26:40.
Jakob's 800 is way weaker than his 5000. I'm fully on board with the take that his best event is the 5000, he just enjoys the 1500 more.
