Ohio State cornerbacks coach Kerry Combs is a man with a very specific set of skills, namely sending players to the NFL.

Coombs caught up with one past and two future first-round draft picks on Thursday during Ohio State's pro day: New York Giants cornerback Eli Apple and 2017 draftees Gareon Conley and Marshon Lattimore.

Considering past cornerbacks like Bradley Roby (No. 31 overall pick of the 2014) and Doran Grant (No. 121 in 2015) aren't pictured, it's easy to see why the Buckeyes can pry the likes of five-star freshman cornerback Jeffrey Okudah out of Texas.

As Urban Meyer likes to say, it's testimony over theory.
