Only potential differences with your predictions I see are as follows:
174: I think Storley upsets Kokesh in semis and beats Brown in a close finals match. Evans takes 4th.
184. Steinhaus beats EL in semis. EL takes 3rd.
197: Burak makes it to Semi's where McIntosh handles him pretty easily. Burak takes 4th.
Hwt: Incredible group of talent at this weight class. I think Nelson beats Telford in Semi's. Telford wrestles back for 3rd or 4th place. McMullen takes 1st place.
