Mock responded to the call and became UNC's first ever All-America selection and national champion.
Today, Lam is calling on Mock again, this time to continue building the UNC program into a full-fledged powerhouse.
When Lam retires after this season, Mock will inherit the responsibility of adding to the prestige that Lam has brought to UNC wrestling during the last 30 years. Mock helped develop that honor by winning individual national championship in the 134-pound weight class in 1982, the first title in program history.
"I feel like it's destiny -- the reasons why he came back, the reasons why he stayed here," Lam said. "I think it's destiny that he takes over and takes (the program) one step higher -- just like he was the first national champion."
If there is one person who can foresee success out of Mock, it is Lam.
Mock did not begin wrestling until ninth grade and did not compete at the varsity level until his junior year.
While most top programs did not pursue him at the start of his senior year, Lam chose to recruit Mock.
"I told him, 'You can go to Penn State and you'll just be another national champion,'" Lam said. "'If you come (to UNC), you'll be the first national champion ever. It'll be a big thing.'"
Mock went on to win the Pennsylvania state championship that year and the likes of Penn State and Lehigh came calling, but Mock remembered who was there first.
