The 6-9, 330-pound Dunlap joined the Bolts as a free agent from the Philadelphia Eagles prior to the 2013 season. He won the battle for left tackle, and protected Philip Rivers' blindside for the past four seasons. His top season came in 2014 when he allowed just 3.5 sacks, tied for seventh-fewest in the NFL among tackles who started all 16 games. As a result, he was named the team's Lineman of the Year.
