Thoughts:
1) Strong by Amos. He knows he can beat Rudisha, Rudisha knows Amos can beat him and more importantly Rudisha knows that Amos knows he can beat him.
2) Rudisha ran a strange race - with a 1.42 guy in the field I don't ever know have D.R thought a 52.5 first lap would be enough from the front with Amos keying off him (and even boxed with 120m to run)
3) Rudisha looked very flat down the back straight. He is obviously not in the shape he was in '12. In his best races DR runs close to 25.0 for his 3rd quarter - tonight he was 27.2 and that is why the field was up his backside at the 600m mark
4) Can Rudisha rebound? 800m running at this level is mental more than anything. D.R is the target now Amos and Aman appear to be well into his head. Also the fact he ran sub 1.43 in Monaco and had younger guys ahead of him. 100 seconds is looking a long way off right now.
5) GOAT? It's not Amos and it's not Rudisha - it's the man who could win drilling guys from the gun, in a big kick finish, in the dry and in the wet. He is also still the 2nd fastest man ever and has an Olympic Silver, Bronze and 3 consecutive World Titles to his name - that is Wilson Kipketer for the time being
6) Not for a second do I believe Nijel Amos is clean
