Chargers acquired DL Sean Lissemore from the Cowboys in exchange for a 2015 seventh-round draft pick. Lissemore was a bad fit for the Cowboys' new 4-3 defense, so he'll join DC Chuck Pagano's 3-4 scheme in San Diego. At 6-foot-3, 298, he's best-suited to play one of the end spots. In 329 snaps with the Cowboys last season, Lissemore recorded 35 tackles and one sack. He'll be the top backup to Kendall Reyes and Corey Liuget. Lissemore showed promise as a run stopper in 2011.
