The development topic is big and probably needs someone to take a deep dive. But I wouldn't put much stock in what Iowa & PSU fans have to say. Not really the most objective bunch.
Victor Voinovich was #15 on the 2021 Big Board and Wyatt Henson was #16. Who has shown more to this point? But Iowa didn't stick with Henson, they replaced him with Real Woods. Seth Nevills was #17 on the 2018 Big Board and was thought to be the best of the brothers. He didn't develop so PSU replaced him with Kervliet.
Regarding the RTC, it won't mean much until John is fully behind it. And that means more than a 20 second sound bite at the golf outing. It means getting out in front and really pushing the RTC forward. That said, I still think it's only 1 (big) part of the development discussion. UPenn has Jordan Burroughs, Mark Hall, Joey McKenna & David McFadden. You aren't going to see them win a team trophy anytime soon. I think we also need to be talking about avoiding injuries, partying, wrestling the right weight class (Collica spent a year @ 141 & a year @ 157), and training methods.
