yeah. i can confirm this is not true. People still think of Iowa. I'm known as the "wrestling guy" - and i'll have wrestling stuff on when i travel.
The questions are usually - "iowa is the best team right?" "didn't that Cael guy used to wrestle for Iowa?" "the toughest guys come out of Iowa right? Iowa high school wrestling is super tough!"
Never mind that its completely wrong on almost all fronts. But Iowa captured attentions and are the Dallas Cowboys of college wrestling. Carl just doesn't do enough. Which is fine, it isn't his style - but Iowa had a prime time feature on ESPN. Iowa still draws the most views of Flo (docs, practices, etc)
So you combine that history with the sheer amount of "things" that Iowa has gone world-wide for - Metcalf pushing Caldwell, Desanto, Spencer's Mom, "Gable" Steveson - where they made sure to remind everyone WHO he was named after.
It ain't always positive. Iowa doesn't always win the big one - but they're still the biggest brand. That stops the day Carl opens up the chest more. Keeping everything a mystery, does exactly that.
