Yes that's the easy thing to say and what i was initially thinking. I mean it's stupid. But what if you wrote a thread, "How to beat the 10k champ in a 5k, let it turn into a hard last 800?" That sounds quite sound.
Farah is basically unbeatable at 5k as he has great strength.
If Hagos tries to push it, then he loses out on the medal as Kejelcha beats him. These guys figure, "We aren't beating him anyway, i might as well medal."
I mean I asked Hagos why he let it go slow and he said they like their kicks. He was happy with third.
ANd he told me his 800 pb was 1:53!! Farah closed in 1:48 .8 so Hagos was likely 1:50 flat.
