The 5-foot-11, 190-pound standout from Springfield High School is coming off a junior season which saw him rush for 2,015 yards and 31 touchdowns. Earlier this month, he opened eyes at the U.S. Army Combine in San Antonio by turning in a 4.35 forty, one of the best times recorded at the star-studded event.
In addition to UK, Koback held early offers from Indiana and Toledo. He was also picking up interest from programs like Notre Dame, Purdue and Northwestern.
Koback was recruited by UK assistant coach Vince Marrow, who was once the head coach at his high school. As a result, the Cats had a nice head start on forming a relationship with the emerging star.
"I like them. I like everything down there. It is a really good campus, good setup, good facilities, really good academic facilities too and the coaches are nice and the players are nice too," Koback told Scout.
He is UK's fifth commitment in the Class of 2017 from the Buckeye State and the second running back, joining Toledo Central Catholic's Michael Warren. He is also friends with UK commit Russ Yeast, the son of former Wildcats star Craig Yeast, who is a top defensive back.
"I know Russ and Mike, and I just felt like it was great move to make. I love UK," he said.
Koback plans to visit Lexington for UK's upcoming junior day.
