With training camps opening around the NFL, Robert Griffin III has finally drawn some interest.

Griffin will work out for the Chargers on Tuesday, Adam Schefter of ESPN reports.

It’s the first report of any team having any interest at all in Griffin, who was the second overall draft pick and the NFL’s rookie of the year in 2012. A knee injury in the postseason after his rookie year changed the way Griffin played, and he’s never been even close to the star quarterback he was as a rookie.

Now he’ll get a shot to show he’s at least in good enough shape to serve as a camp arm and perhaps a backup to starter Philip Rivers.

Behind Rivers the Chargers have three quarterbacks on the depth chart: Kellen Clemens, Mike Bercovici and Eli Jenkins. If Griffin is even close to the same player he once was, he’s an improvement over any of those three backups. But whether Griffin can ever return to form remains to be seen.
