Yes, like winning world juniors? That's choking? She is a second year senior, still learning to race. She also isn't very fast (58sec for 400m - her listed PR) so will get hammered by anyone with even decent leg-speed in a slow race. She did what she needed to do in the 1500m here, without having to lead the entire race, then came back strong the last 100m to get a medal.
Her 5000m still needs work - as seen by the meltdown (although big 14.54PR) in the Diamond league race against Huddle over the last few laps. Whether she can handle the work-load required down the road I don't know, but I see her moving to 5000m/10000m as did Radcliffe before her, and leaving the 1500m behind. Whether she can run with the African women may be another matter, and that will determine whether it is even worth it to move up, if she is going to get beaten anyway. But, if done right, I see her getting to Radcliffe's level for 5000m before she is done.
