Dropping to 3:32 from 3:37 may seem dramatic, but we're talking a 3:30/3:46 (3:53 high school runner) with 1:43 800 capability and 27:30 10k capability. We're also talking about someone who debuted this season at 3:54 ... in the 1500. What's 3 seconds when 17 seconds was easy?
Since running 3:43, he has slowly chipped away at that time. 3:32, if the trend keeps up, seems very possible. Slower than 3:34 frankly seems improbable.
It's Webb, so you never know, but his progress has been smooth and incremental, and his head seems like it's in the right place.
