Barring injury, Philip Rivers will be the Chargers’ starting quarterback — just as he has been for 185 consecutive games.
But who will back him up? The incumbent is Kellen Clemens, a 34-year-old journeyman who has held the second-string role for three seasons, and re-signed with the Chargers in March on a one-year deal. Mike Bercovici and Eli Jenkins — who went undrafted in 2016 and 2017, respectively — round out the offseason depth chart.
And on Tuesday, the Chargers worked out Robert Griffin III, the former No. 2 overall pick whose career has sputtered since his transcendent rookie season.
It was his first visit with any NFL team this summer, a steep fall from his star-making entry into the league. Less than five years ago, Griffin looked like a franchise savior in Washington, racking up 3,200 yards through the air and another 815 on the ground. He totaled 27 touchdowns, and ranked third in the NFL with a 102.4 passer rating.
But injuries derailed his career, and in 2015, he found himself benched in favor of Kirk Cousins. Griffin resurfaced in Cleveland last year and won the starting job — but fractured his left shoulder in the regular-season opener. He eventually returned to play in four more games, finishing with a career-worst 72.5 passer rating.
Which is to say that, no, he won’t be pushing Rivers, a six-time Pro Bowler, for practice reps. Even first-year coach Anthony Lynn, who has left just about every starting job up for grabs, said in mid-June: “I think we’re straight at quarterback.”
But Griffin would certainly be more accomplished than anyone else on the Chargers’ quarterback room. And with training camp set to start in Costa Mesa on Sunday, he represents a low-risk option to supplement the depth chart.
The Chargers have been open about needing to find a successor for Rivers, who turns 36 in December. But they have not drafted a quarterback since using a 2013 seventh-round pick on Brad Sorensen, an approach that leaves them…
