Washington State was the first to offer Griffin and then Montana followed suit later that week.
"It was real relieving to get those offers," said Griffin. "Washington State was big because it's the Pac-12. I was excited. I didn't believe it at first. I was in shock. I know more are going to come in so I have to work harder."
Griffin was planning to see Washington State and BYU this week, and BYU could be offering soon.
"We had a lot of schools come through and were really interested," said Griffin. "Nevada, UCLA, USC and Arizona State all came by. Coach (Clay) Helton came by from USC and invited me to Rising Stars, Coach (Jeff) Ulbrich from UCLA came by and they want me to come to camp and Coach (Chris) Ball at Arizona State also came by."
Griffin said everyone is looking at him as a corner, and he's hoping to continue to add weight by the fall.
His half-brother is four-star linebacker D.J. Calhoun from El Cerrito and the two have talked about playing together in college.
"That's one of our big goals and I would like to do that if possible," said Griffin.
