Seattle selected Unger in the second round of the 2009 NFL Draft and he became the starting right guard during his rookie season. The next season, he moved to center and spent the rest of his career there. In 2012, he was named offensive captain and was later named First-Team All-Pro and selected to the Pro Bowl. Unger repeated as a Pro Bowl selection the following year and was the starting center for the Seahawks’ Super Bowl XLVIII win over the Broncos. During the 2015 NFL Draft, Unger was packaged in a trade with the New Orleans Saints for tight end Jimmy Graham. Unger played in New Orleans for four more seasons, earning a third career Pro Bowl selection in 2018, before retiring in 2019.
