Coach Manning sure seemed to develop "Jordan Burroughs". As a coach, has been in the top 10 in NCAAs 9 times out 18 years including the last 4 and should be this year. I think college programs in Indiana would take his success rate at developing all-Americans.
Wrestling in college is tough and a lot of reasons why kids don't get to the AA status. Its a mental marathon, kids are used to being the Alpha wrestler and get to college and you're just one of the guys. Finding your way to motivate yourself can be extremely difficult. Some kids peak earlier and some get girlfriends and see other distractions. Lot of cool stuff going on at colleges also like learning, maybe some kids just don't dedicate their whole life to it. Chad Red Jr is still top 20 so still doing pretty good. Look at the ranks of Mannings upper classman. Maybe Chad Red is still going through his system to get him there.
