Will all due respect AnklePicker, I think Mphillips is right, and you'd have a hard time convincing the rest of the world that Seniors isn't the litmus test. A couple of things . . .
Hard to consider us the best wrestling country right now given our poor showing at 2024 Olympics...three total medals and no gold- the first time in 56 years. We finished 3rd (4th if you count Russia), so that doesn't equal best. And no golds in non-Olympic weights either.
As OP suggested, I believe Jordan Burroughs was a catalyst for this recent "Golden Age." I was at Worlds in Budapest in 2013 for the dark days- when we only had one total world medal, a gold by Burroughs on a bum leg. At that point, he was USA Wrestling, and these kids now at U17/U20/U23 were grade schoolers who idolized him.
I'm just as excited about this young crop as you (and everyone) are- I'm very hopeful that they can have the same impact in college and at the Senior level...time will tell, but we've never assembled this much talent at one time. It's exciting!
