What happened: Mack entered the record book with a six-sack performance for Los Angeles, joining one of the league's rarest single-game clubs. The Chargers are back on CBS at 4:05 p.m. ET on Sunday.
Why it matters: That benchmark still frames the ceiling of Mack's impact as Los Angeles heads into another regular-season test. Earlier this month, Mack was tipped for a rebound season with the Chargers, keeping the focus on whether he can still tilt games off the edge.
By the numbers: Mack became the fifth player in NFL history to post six sacks in one game.
What to watch: Sunday will offer the next read on Mack's pass-rush role and whether Los Angeles can turn that pressure into a needed result.
