To say Joey Bosa only focuses on football during the season would be an understatement.

The San Diego Chargers rookie spent Tuesday signing autographs at his team's blood drive and getting to know his new community. A big part of that community has been quarterback Philip Rivers, who is known for having an ever-growing family of eight kids.

With his mind focused on the game, Bosa didn't know about Rivers' famous pack of children until recently.

"I didn't know about all of his kids," Bosa told Mighty 1090 when asked about the "one thing" he didn't previously know about Rivers. "I didn't know he had a whole friggin' troupe behind him."
