Exactly right. He missed a bunch of matches without any real explanation. There were rumors about him quitting the team. Dresser dismissed those rumors and said he was missing time because of a "family issue." Then after he came back and everything was going OK, Dresser was a little more candid about what was going on. This is from a story in the Roanoke Times right before NCAAs:
BLACKSBURG — Zach Epperly once was a bit lost, but now he’s found.
The Christiansburg High School graduate missed six Virginia Tech wrestling matches in January, even though he was healthy.
The 2015 All-American is one of the nation’s best wrestlers in the 174-pound weight class, yet he was not in the lineup.
“His head wasn’t in the right place,” coach Kevin Dresser said. “We needed to pull him out and get his head right. ...
“When you’re not in the right place mentally, you’re not as disciplined with your weight and all that kind of stuff. He wasn’t ready to go from just an overall training standpoint. He wasn’t ready to compete … physically or mentally.”
Sounds like maybe he just got worn out.
