Greenlaw will serve as one of the two starting inside linebackers in defensive coordinator Vance Joseph's scheme this fall.

"I was a foster kid growing up, so there's not a lot of times that people just wanted me," Greenlaw said. "It just made me feel special. It made me feel like this is the place where I needed to be."
