Will have to disagree with you on Karam, but I guess that depends on what your expectation of what a big 126lber is. I've got a kid I consider part of my family who has wrestled him in a state title match who I don't consider smaller than Karam and he walks around at 130 to 135. Walking around weight varies a lot from kid to kid.
I'm talking frame here. For example, we have a kid who was nationally ranked last year at 106/113 on our HS team. He walked around at 140 plus this summer - 10 pounds over the kid I just mentioned. I consider him to be smaller and a weight class less than the kid I mentioned. So does most everyone else.
I'm not privy to Fix' walking around weight, but don't dispute that it is a lot. His frame is different from the kids I mentioned. I would be very surprised if Fix projected at a higher weight in college than those kids or even the same weight early on. Again, JMO that his frame looks a weight class below AND he has been competing against guys like Spencer and such, who definitely are smaller at this time.
Would not disagree one bit about Karam's program, access to Lehigh and being a matchup nightmare - I know this well. I've always had the utmost respect for him and have known he belonged in the elite category for a bit now. I definitely don't consider him a large 126lb, but I guess you could say that comparing him to just your run of the mill HS kid. But not compared to most of the kids that he's wrestling in the last few matches when he's going for a state title.
Fix' frame reminds me of a kid like Wade Cummings, or maybe Pletcher would be a more well known kid. And these kids are kids that project at 125 and 133 in college and are bigger than Fix right now no matter what he walks around at.
