The odds of anybody going undefeated in their college career again is pretty low. Even the guys who we think are can't miss end up missing. And even the can't miss guys lose a match. For as good as David Taylor was didn't even win 4 titles. Kyle Dake and Logan Steiber both won 4 titles but they lost along the way. Dake only had one undefeated season. Zain is likely going to finish with 3 titles and probably be undefeated his last three years wrestling. I'd be surprised to see Nolf lose again, but he has two losses in college.
And then you have guys like Chance Marsteller, who beat a college kid or two at the NLO as an 8th grader. He was a rare undefeated HS 4XPIAA state champ. He couldn't even get in the starting lineup at Okie State. And since he has straightened things out at Lock Haven he still lost. Heck, even Spencer Lee is not an undefeated HS wrestler, and he didn't win 4 PIAA state titles. Lee won't even be an undefeated NCAA wrestler and he is as good a prospect as we've ever seen. Nick Suriano? Undefeated NJ 4X Champ? He lost in college. Kyle Snyder? Morgan McIntosh beat him at the NCAA tournament.
Even the best guys lose at this level.
