600m indoor WB has long been the weakest middle distance record.
When you have someone like Cas Loxom running 1:14.9 you have to consider the quality of that time.
1:14.8 is still weak, but nice run anyway.
Yes, I remember the same comments about Korir's performance last year. People were very unimpressed with it. Saying a whole bunch of negative things (for some reason).
Then Korir ran 1:43.10 last summer (the world leading time). Pretty good for an NCAA runner. Massive progression.
Now the same coach has a guy who is even faster in his hands.
I never said he isn't a good runner. It's a great time and a good run. I'm sure he is 1:43/1:44 material. If not faster.
The point I'm making is where is Rudisha, where is Bosse on that 600m indoor list? It has not been attacked by the big names over the years and so is weak. The WR should be in the 1:13.5 region.
I don't remember Korir doing that well against the big boys when it mattered neither.
