Pretty sure it's Miruts Yifter, not Myrus. Myrus is like some bad contraction of Miley & Cyrus.
I had a different interpretation from a lot (but not all) of the people on this thread.
Mo's kick: I think it was just as good as usual. Edris closed in 52.4. Mo was right behind. So Mo was 52-high, or 53-low. Isn't he usually 53-low? Legitimately asking, has Mo closed in 52-mid, ever, in a 13:30 race?
Ethiopia's team tactics: It looked to me like they were deliberately trying to create a wall that Mo couldn't get around on the last lap. And it looked to me like it worked. If only Yomif hadn't ceded the inside lane, Mo might have had 3rd or 4th. I think the plan was for Barega to get up on the outside as well, but they were moving too fast and Barega just couldn't get there.
Mo's tactics: I don't think Mo was trying to "go" with Butchart. I doubt he feared Butchart. Instead, I think he was trying to follow the sacrificial lamb (Butchart) plowing the road and breaking the wind for Mo, allowing Mo to go early before the Ethiopians could wall him in (which they did). Mo was also wise not to try to go wide on the back straight to get around the Ethiopians. At the speed they were moving, he would definitely have wasted too much energy.
Other tactics: It looked like athletes from multiple countries talked before the race, in an effort to try to bury Farah. I say this because they were all trying curiously similar things. Chelimo goes to the front on lap 1, only to fall back. Tiernan goes out, perhaps to draw Farah, but Farah doesn't take the bait. Multiple athletes trying to box him a bit. I liked it. Some serious position-jockying was fun to watch!
Pre-race introductions: I really loved the individuality that many racers sported during their introductions. They all had some kind of gesture, and track & field needs more individuality like this. For that matter, did anyone see Chelimo's mobot followed by a head-shake and a throat-slit? Genius!
