Let me analyze a few arguments on here.
The thing is, Farah, in 2015, ran a 3:28 1500m, an 8:03 2-mile, a 26:50 10000m, and 2 x Mid-59:xx Half-Marathons within HALF a YEAR. Of these, the 3:28 1500m and one of the Half-Marathons were run within TWO MONTHS of each other. You can credit Aden, drugs, doorbells, whatever, but Barega, Cheptegei, and the others are utterly pitiful compared to that.
What's your point? In the last year, Kejelcha has run the equivalent of all of those times and he got smoked by Hagos yesterday. Here is what Kejelcha has done in the last 12 months.
3:47.01 mile - equivalent to 3:30.15 1500 - Farah's pb is 3:28.81
7:28.00 3k - equivalent to 8:03. 2 mile (same as Farah)
12:46 5k - Farah's lifetime pb is 12:53
26:49 10 k - Farah's pb is 26:46
59:17 half- Farah's pb is 59:22
Besides Bekele and Gebrselassie, there are likely no other runners that would be able to top Farah during his prime.
What are you talking about ? Jeilan smoked him on the last lap in 2011 in the Worlds 10,000. The reality of that loss and his loss to Edris in 2017 is simple - Jeilen and Edris were better than Farah on those days. I don't want to hear crap about how it was before and after Farah's prime.
In that 5000 in 2011, Farah closed in 53.3 - the fastest he ever closed in any championship 10,000 that he ever won and yet he lost as Jeilen closed in 52.8.
In 2017, Farah lost because Edris closed in 3:57.6 - which is faster than the 3:57.7 that Farah closed in to win a similarly timed Worlds in 2013. Edris' last lap was 52.4 to Farah's 53.4 in 2013.,
So those two examples show when someone comes up with a close that is half a second or a full second better than what Farah has done in the past, then Farah loses. Add in the fact that Kejelcha - basically the same as Farah at every distance - was a distant third and I don't think it's crazy to think Hagos would beat him.
It's hard to appreciate the greatness of Hagos' run because it was run in front of zero people with a guy filming it on his phone, but it was world class.
