Santos is projected by Big Red Report among many media outlets to be the starting MIKE linebacker in the fall.
In 13 games last season, he recorded 24 total tackles, registering one start.
During the spring, Santos was moved from MIKE linebacker to WILL for a short time, but it appeared it was by design to help the third-year player understand all the linebacker positions better.
"I really think it's a mental thing to help you understand the defense much better, especially with the younger guys. You have to know the job next to you," Santos said at the time.
"I know pretty well what's going on, especially playing multiple positions. I think it helps...It creates competition, but personally, I don't get too comfortable. Everyone that came in has talent. It's college football. I don't look at it as 'I have the MIKE spot lined up. I don't want to take anything for granted or regress as a player."
