Sam Tanner just ran a 3:34 1500m indoors for the NCAA record and can run a 48 sec 400m. A couple of things to note also: He's young -only 20 and has had very little experience running qualifying type races, more just straight finals. He failed to qualify in the mile due to this lack of experience. He was tried to just qualify for the final and conserve as much energy as possible. Unfortunately that backfired a bit but I'm sure he has learnt a lot from it. He has an exciting future ahead.
