This is my personal opinions....
In 2016-7 Kollin, as a rs-freshman, really didnt cut much weight, at all. And wrestled like his hair was on fire.
In the summer of 2017, he made the junior world team at 96 kg, so bulked himself up for the weight. I recall, in an interview, saying he hit 220 (but my memory could be wrong).
This past year, 2017-8, he had to cut weight to make 197... and IMHO, it really showed. He was not the same at duals, with wrestling 1 hour after weigh ins.. and in the early rounds at tourneys. In Vegas, he was mediocre in the early rounds, then was himself by the later evening matches, even pinning Haught in the finals.
I told my other Buckeye fans that my biggest worry for Kollin was the quarter finals on Friday AM. If he could get by quarters, then semis and finals would be 6-8 hours after weigh ins, and he would be fully recovered. Unfortunately, I was correct and he lost in the quarters.
He was able to beat Darmstadt on Saturday morning... but IMHO, he will always beat him, as that goes back to high school. Then lost to Connel again, Saturday AM, few hours after weigh in.
I have no idea if I am right. But if so, I hope Tom makes him slim back down and be around 200-205. I heard recently he was around 210, in an interview.
