Virginia Tech has earned a reputation for its production of NFL defensive backs, and Chuck Clark appears to be next in line.

Clark, who's being evaluated as a free safety at the next level, has gone through separate on-campus workouts with the New England Patriots and Cleveland Browns, as source tells Sporting News, adding that the workouts included on-field drills, film sessions and chalk talk.

Clark started 40 games in four years with the Hokies. He made 296 total tackles and defended 23 passes.

The majority of Clark's playing time at Virginia Tech came at cornerback. He also was a regular special teams contributor, a role he certainly can play in the NFL.
