Early life
Frey was born on April 6, 1990 in Roseville, California. Frey's father, Demetryst Cornish, is a Walter Payton fan, and therefore named Frey's dogs "Bear" and "Payton." Frey and linebacker Lance Briggs were also from the same area.
"The only person I have an idea about is Lance Briggs just because we’re from the same area. He was a stud back in Sacramento and everybody knows about him. I’ve never met him; I’ve just heard stories about him."

During his year as a senior, Frey was named first-team all-WAC after tying for first in the FBS with 21 pass breakups and recording a career-high five interceptions.
Professional career
Chicago Bears
Though Frey was projected to be an undrafted free agent, he was picked in the 6th round, 184th overall by the Chicago Bears in the 2012 NFL Draft.
"Frey gives the Bears an athletic corner with athleticism and quickness. He is ideally suited to play in a two-deep scheme and will have a chance to make the roster as a sub defender."
