My reasoning for selecting Nebraska was their two highly ranked guys. Lovett is a very solid wrestler but has no where to go but down (SVN, Henson, Gomez -has beat Lovett twice, Mauller would all be formidable opponents). Also, just don't really know what to do with Robb and how he will respond to the injury/recovery. For what its worth I hope that he proves me wrong and as a result Nebraska outperforms their seed.
My reasoning for selecting OK State was basically opposite for Nebraska. I think they have a couple guys with upside (Sprately, Alvarez, Thompson) and their highly ranked guys are pretty solid bets to place at/near seed (Fix, Plott).
