One of the younger brothers of Minnesota Vikings runningback and Stanford graduate Tony Gerhart, in 2011, Garth garnered Second Team All-PAC 10 honors for his blocking at center for Brock Osweiler and the Arizona Sun Devils. A 4 year letterman that played in 39 games with 35 career starts, Garth played all the interior positions of the line for the squad, and also appeared in the 2012 East-West Shrine Game, and the 2012 Senior Bowl.
At 6-2, 302, Garth was invited to the combine, ran a 5.29 40, and bench pressed 225 lbs 25 times. A big-motor guy, who puts in good effort, and finishes blocks strong, Gerhart is considered a leader among his peers. Garth was viewed as a late round prospect, but ended up going unselected in the 2012 draft. The Cleveland Browns signed him to a free agent contract shortly after the draft concluded. Since that time Garth has bounced around the league splitting time with the Packers and Panthers. He was promoted from the practice squad and signed to the active roster of the Packers before the beginning of the 2014 season and played in 2 contests.
