This past week Nike Oregon Project announced the addition of 2016 Olympian Clayton Murphy to their roster. Murphy joins Matthew Centrowiz, Eric Jenkins, and Craig Engels to form one of the top miler quartet training groups in the world.

Imagine if we got to see this newly formed group run a 4xMile against other top U.S. training groups next year? I think it's safe to say Ireland's 4xMile world record of 15:49 would get shattered.
