I don't think Gentz beats Rotondo or Campos. Gentz has some wins a big tournaments, but those brackets were pretty weak.
Robles, I don't think he get's passed Talavera, Robles has had several losses this year. He lost to Snediker, Neal among others. He's a nice kid but should have cut to 138. If Robles get's passed Talavera I think it's a longshot to beat Orrino. Robles has I think a couple of losses to Fu. I know wrestling math isn't exact but if Orrino, beats Snediker, that has beaten Robles a couple of times, and Fu that has beaten him twice this year, not sure how you figure he'd pull that off.
Eaglin is a solid pick, I've heard 'rumors' that Robles was going to cut to 138, and beat Eaglin regularly. Just hearsay. Maybe coaches would let him drop. If Robles was in 138 I'd favor him.
