Imo, the old "Iowa Style" works well at developing good wrestlers but it will only get you so far, especially with or against elite wrestlers. So, we get exactly the results that we get. Bringing in some technical expertise on staff to work with guys on scrambling, chain wrestling, finishing shots would fix a lot of tactical issues at Iowa right now. Changing the culture of the program would also pay huge dividends, but it's a longer-term issue to be fixed.
A huge competitive advantage that Iowa has is the structure and individual attention that Iowa gives its wrestlers. A lot of kids need a solid framework like that in order to thrive. Look at DeSanto, for example.
Cael's relaxed and "fun" training style isn't for everyone. Guys like Gavin Teasdale, Nick Suriano, and Andrew Long struggled without guardrails and a lot of rigor in place. It's not too different I think from the way students can sink or swim when they go from the structure of high school to the autonomy of college.
