5/10 - Made a point and cited a source before disparaging it.
It's up to the pace that gets set and somebody else's willingness to follow that pace. He's going to run with the pack. Many guys here are trying to win the Diamond League points race and they will want to run their ideal races as a priority. If one of them is a strength runner, then you might see one go with a pacer. Rupp only breaks 12:53 if other runners break 12:50, which I don't see happening.
