FILE - Cleveland Browns guard Garrett Gilkey (65) during an NFL preseason football game against the St. Louis Rams in this Aug. 8, 2013 file photo taken in Cleveland. Ridiculed as an awkward high school kid, Gilkey knows the pain of being bullied too well. Cleveland's rookie offensive lineman, who has become an anti-bullying advocate, can't fathom the suffering endured by Miami's Jonathan Martin, who left the team last week because of emotional issues. "I can't imagine what he has gone through the past year and a half," Gilkey said of Martin on Tuesday Nov. 5, 2013 as the troubling situation with the Dolphins became a bye-week topic for the Browns.
