Yes, some assumptions were made. But generally, if someone is significantly banged up or ill, there is some outward sign of it. Sometimes those signs are very subtle, and if you do not know the wrestler well, they are very hard to see. I'll give you Nick Lee was nursing something the second half of this year, and Sebastian Rivera had something off. I saw nothing from RBY in any matches I saw, to say he was hurting, and I saw quite a few of his matches this year. Quite the opposite, I thought he was more aggressive than usual, and often looked better than I have seen him look in the past.
You can tell yourself whatever you want to make yourself feel good, but Spencer has not had a fully healthy season since he's been at Iowa. Marinelli only had one completely healthy year, everyone knows Kem has been banged up a lot. As has been stated in many threads on this board. Iowa needs to take a hard look at our S & C practices and how we run practice as a whole, because we have had way higher than average injury problems for some time now. This year it reached epidemic proportions.
Eight pounds, at the D1 level is a significant thing, but Spencer is not just an above-average wrestler, he is truly elite. RBY may be elite too, but if so there are different levels of elite. As I said, this will likely never happen, so we'll just have to believe what we believe and agree to disagree. I would really love to see it though.
As for your comparisons, He has only wrestled Suriano once in college, and tore an ACL in that match. Sure, he didn't major him, but controlled the entire match and probably stayed conservative because; A. It was the NCAA finals and no reason to run up the score, and B. The knee probably was telling him to take it easy. Suriano was never a threat in that match. He has not wrestled Fix in a folkstyle match in college (or maybe ever?), but his freestyle matches against common opponents the past few years gives him a huge advantage, except maybe in the height of Fix's PED days. We'll likely see that match-up in years to come. I also hope RBY sticks around for US Senior matches. He will not be competitive at 65kg, maybe OK at 61kg, but I would look forward to seeing him try to make 57kg, then we might see for sure. RBY is better than Fix is definitely your opinion. I'll give you that he had a legitimate takedown this year, but last year he just got away with stalling better.
