One topic that was brought up was his father, who reportedly came into the Redskins' locker room after the team was beaten 27-6 by the San Francisco 49ers on Monday.
Griffin completed 17 of 27 passes for 127 yards against the 49ers and has thrown 11 interceptions this season, six more than he had in his rookie season.
On the subject of his father, Griffin said he is not going to stand for people making comments about his family.
"I don't know what all has been said, I just know it hasn't all been positive," Griffin told reporters. "My dad came to check on me. He came to check on me to make sure I wasn't injured. Mom was upset. He wanted to, you know, do his fatherly duties and step in there and see if I was OK."
"Anybody out there that's going after my dad needs to back up," Griffin said. "That is my father. I will protect my family. He served 21 years in the military. I know that's not an excuse for anything that he does, but he's not overstepping any bounds, so I respect that. I hope people will respect that."BURKE: Colin Kaepernick returns to form, Robert Griffin III struggles as 49ers drop Redskins
