Let's be real here. The field and the weather could've produced several sub 13:22's if the field had gone out together controlled in 64-65 and been steady until the last 600-800m. But Chelimo did what he did and went out like a madman in 57. Say what you want about Kincaid, but where was the guy going to go after an opening 1k of 2:30 (that's well under world record-pace). I was surprised he was still there at the mile in 4:07 (his PR is like 4:01). Of course he wasn't going to lead, where would he go from there? No way he would've been there in the end if he'd kept up hammering from 1600m - 3k. Honestly, I was surprised Kincaid hung on and responded so well over the last lap. Even the announcer's had written him off with 600m to go.
Bottom line - you rarely can attempt a qualifying time and race to be in the top 3 at a US Championship. Too many tactical and weather factors involved in both objectives. It was an exciting race and the finish times were what they are.
Really the travesty is the for some unknown reason the USATF unlike the rest of the world has chosen not to use the entire qualifying window for the World Championships which goes until Sept. 6, that's six weeks away. Worlds isn't even until 9 weeks ago.
