The 6-4, 220-pound Griffin committed to San Diego State on Monday night.
"I committed to Coach (Tony) White and he was jacked," said Griffin.
Griffin, who also had an offer from Fresno State, loved what the Aztecs presented both on and off the field.
"The academics were good and it's a good football program that I think would use me best," said Griffin.
Griffin was one of two linebackers to commit to the Aztecs on Monday, joining Brawley (Calif.) linebacker Donavin Buck, who committed to San Diego State earlier in the day.
