Below are 10 quick-hitting insights entering the Chargers' Week 13 matchup against the Pittsburgh Steelers.
1) The Chargers' last Sunday night game came on Dec. 7, 2014, a 23-14 loss to the New England Patriots. Only six current Chargers played in that game: quarterback Philip Rivers, tight end Antonio Gates, wide receiver Keenan Allen, defensive end Melvin Ingram, safety Jahleel Addae and defensive tackle Corey Liuget, who was placed on the reserve/injured list before Week 12.
2) Sibling rivalry: Sunday will mark the first time that fullback Derek Watt will face his brother, Steelers outside linebacker T.J. Watt, in the NFL. The two were teammates at Wisconsin for three seasons. Running back Melvin Gordon was also a college teammate of T.J.'s for two seasons.
3) Both of Derek's brothers are top-seven NFL sack leaders. Entering Week 13, T.J. has 10 sacks. His older brother, Texans defensive end J.J. Watt, is third in the league with 11.5. Collectively, the Watt brothers have a record of 23-9-1 this season.
4) More brother connections: Centers Mike and Maurkice Pouncey will play in the same game against each other for just the second time in their NFL careers. They have a combined nine Pro Bowl appearances between the two of them.
5) Philip Rivers and Ben Roethlisberger both come from the famed quarterback class of 2004. Roethlisberger ranks seventh all-time in passing yards with 54,729. Rivers is eighth all-time with 53,467.
6) Someone who coached both quarterbacks is Chargers Offensive Coordinator Ken Whisenhunt. Whisenhunt was the Steelers' OC for Roethlisberger's first three seasons in the NFL (2004-07) and helped lead Pittsburgh to a victory in Super Bowl XL. He's spent four total seasons as the Chargers' offensive coordinator.
7) Could Sunday's game be decided in the second quarter? Los Angeles has outscored its opponents 124-41 in the second quarter this season. Pittsburgh has been just as dominant in the 15 minutes before halftime, outscoring teams 121-46.
8) Both the Chargers and Steelers had recent six-game winning streaks snapped by the hands of the Denver Broncos. The common theme? Giveaways. Pittsburgh turned the ball over four times, L.A. twice.
9) Away from ROKiT Field at StubHub Center, Los Angeles has committed just four turnovers in six games. The Steelers have forced one or no turnovers in nine of 11 games this season.
10) Chargers safety Jahleel Addae is friends and former college teammates with Steelers All-Pro wide receiver Antonio Brown. Earlier this year on Chargers Weekly, Addae recalled his first interaction with Brown:
"I took a visit at (Central Michigan) and (Head Coach Butch Jones) paired me up with this guy named Antonio Brown. I didn't know much about him, but at my visit I learned that he was a freshman All-American, punt return, wide receiver, and he was from Florida. It was a coincidence, he's from Miami, I'm from Tampa, and we just clicked since then. I played three years with him, hung out with him, trained with him. He introduced me to Bible study on campus – a real big brother to me when I was at Central Michigan."
