The Los Angeles Chargers want Khalil Mack back, even Jim Harbaugh and general manager Joe Hortiz haven’t been shy expressing that in public. But whether the Chargers can actually prevent Mack from leaving in free agency is hard to say.

After the Los Angeles Chargers lost to the Houston Texans in the first round of the playoffs, there were major question about Khalil Mack’s future with the team. He’s still posting solid production, but he’s aging rapidly, and the Chargers had so many other free agents they needed to retain.

Edge rusher Khalil Mack was set to become a free agent this week, but he never made it to the open market. The Chargers and Mack agreed to a one-year deal that will keep the veteran edge rusher in Los Angeles for a fourth season.
