I was impressed with his last 800M (1:51.x) and last lap (53.6), but mostly how effortless it seemed for him. This kid seems extremely fit right now and should he sharpen over the next 2 weeks might be tough to beat, especially in tactical races, which are commonly seen in National championships.
The other factor is nerves for the Pro guys who have everything to lose vs. the collegiates who have squat to lose - Should he stay sharp, I'm betting he makes the final and competes well for a spot
