61 KG - Magomedov wrestles a Russo from Belarus in the semi-finals. The guy has been at Cadets and Juniors, but never seems to get any wins there. Meanwhile Magomedov is ranked ~#11(?) per Flo, is 4W-2L in professional MMA, and was Russo's #1 ranked gent heading into Russo nationals. I expect Chlebove to be pulled back in.
74 KG - O'Toole has Sonny Santiago, O'Connor's replacement at 157lbs for North Carolina in the semi-finals. I expect he wins with ease. Of note: Santiago looked a full weight class smaller and ground out a win in his QF.
86 KG - Brooks has Russo's #1 ranked wrestler in the semi-finals. This should tell us a lot how he stacks up against the international competition. Wrestling DT and ZV close are one thing. I don't even know if I would call this a toss-up... I think Brooks is the dog here. I think he will win, though.
92 KG - Very real chance the Turk loses next round. The Turk has lost to Iboyan of Armenia many times this year in the U23 and U20 curcuits. The gent he faces next beat him in Round 1.
125 KG - Haven't seen anything of Khosonov aside for a 5th place finish at Euros (he went 0W-2L losing to Geno and Hungary). I think the Russo was the biggest competition he was going to face with Masoumi not being allowed.
So it actually looks like Cardenas has the least likelihood of bringing home a medal at this point, of the five gents we have in right now.
