First off, the teams ran very well at Notre Dame. All I'm saying is that the missing rail was worth 2 seconds over the 4k and when you also factor in the benefit of the over size track you see that the teams were pretty much on the money at nationals.
As regards other events, the milers were only picking up .7 from the rail and another 1.2 from the oversized track. So, I'm claiming that the guys who ran 3:57 - 3:59 there were realy worth 3:59 - 4:01. For interest let's compare the times at ND and see how they progressed at the NCAA qualifying rounds:
1 Knoll, Shane 3:57.36# (4:05.05, nq)
2 Emanuel, Lee 3:57.91# (4:01.61, Q)
3 Switzer, Justin 3:58.86# (4:01.55, Q)
4 Boone, Jacob 3:59.07# (4:01.80, Q)
5 Davidson, Mark 3:59.97! (4:04.69, Q)
So, by and large, those guys did well at the meet, with 4 of the 5 making it to the finals. Admittedly, nobody has pb'd yet, but, then again, championships tend to be tactical.
All the guys who qualified off of 200 meter tracks made it into the finals. They put Centrowitz into the finals even though he finished eleventh --- the Oregon factor.
