As huge follower/fan of JO since he was in 9th grade and a die hard PSU wrestling fan (and season ticket holder), I think this whole situation sucks.
Assuming the OP is correct and JO does have a valid argument, I think an unplanned wrestle off will be unfair to both guys. Zain has his training and weight management built around the assumption that he would wrestle competitively yesterday (with a 2KG allowance) in Spain and then again at scratch weight at the end of August in Paris. Meanwhile, JO must be flying blindly as to how he should managing his weight and training.
It seems to be that the basics of JO's (and his lawyers') argument had to be known at team trials. Again assuming the OP is correct and this argument has a decent chance of ruling the day, they should have let JO wrestle in the trials and then hit him with the suspension immediately after. That way, if he wins his appeal, the PLANNED on the mat wrestling would have decided who was on the team...Not a wrestle off on an odd date that neither guy was able to prepare for properly....If he lost his appeal, whoever took 2nd at trials would get the spot.
Of course if USAW looked at it said, No way JO is winning this appeal, then they did the right thing. But the longer this thing goes without a ruling, the more likely it appears that a wrestle off may actually happen.
As for the matches themselves, I really wanted to see it. There is no way JO was going to hit a CORRECT THROW at the buzzer for the win again. I'm sure Zain would never let that happen. He learned from the Vegas bout. It also seems that Cael/Casey got Zain out of that really bad habit he had of going hands to the face so often. Zain gave the ref no choice but to make that call against him at the US Open. But he now seems to have that fixed.
On the flip side, without the hands to the face defense, I strongly suspect JO would get to Zain's legs and score --- but who would score more? Keep in mind Zain never took JO down either.
Regardless of the victor, I really wanted to see that bouts ---- at a time when both guys had planned for it. Both are phenomenal wrestlers. I tend to think JO is a little better now, but Zain will eventually own the weight (or whatever weight he ends up at after the new weights are announced -- assuming he does not end up at Stieber's new weight).
The longer this drags out, the more likely it seems the wrestle off is going to happen. If this was open-and-shut, we would have heard something by now.
Frustrating.
