This is wrong. PSU's recruiting dominance follows from the gains that the wrestlers make when they go there. Look at the 2022 recruiting class. Ohio St's #1 ranked "Young Bucks" class had 4 top 20 recruits including the top 3 overall. Penn State had one top 20 recruit in that class - Levi Haines (who was ~15). Two years laters, the results for the two classes:
NCAA titles:
Young Bucks 1 - Haines 1
Finals Appearances:
Young Bucks 2 - Haines 2
Hodge Finalists:
Young Bucks 0 - Haines 1
While I doubt anyone at Ohio St is disappointed in the "historic" Young Bucks class, Penn State has gotten as much from their one guy right out of the gate.
In addition, #42 recruit Braeden Davis was the #1 seed at NCAAs as a true freshman. #59 recruit Mitch Mesenbrink transfers in to Penn State before his freshman year and makes the national finals. Unranked room guys Terrell Barraclough and Lucas Cochran both beat AAs wrestling up a class in spot duty. Penn State is getting more out of all of their recruits at every level - the blue chip recruits, mid-tier recruits, and room guys all show more development and better results than at other places. That is either due to superior coaching/training methods or an ability to identify underrated recruits across the board (seems likely to be the former).
Given that Penn State is getting better results from their guys who come in at every level, is it any wonder that the blue chip guys are seeking out Penn State now? The program itself does the recruiting because of the coaching/training.
Obviously, Penn State doesn't "hit" on every recruit, no one does, but most of the misses among their blue chip recruits are due to either injury or off-mat issues (e.g. Altons, Teasdale, Howard), and they are relatively few and far between. In addition, Penn State hasn't had much success with portal guys, especially in the short term (Hildebrandt, Conel, and Nagao/Truax all regressed), but that is a sign that their success is based in the guys they get in the room and train in their way from the start (or at least before their freshman years in the case of Mesenbrink or Kerkvliet if they are not officially PSU recruits).
