The Facts: Locker is walking away from the NFL. "I am retiring from football after much reflection and discussion with my family," Locker said in a statement. "I will always be grateful for having had the opportunity to realize my childhood dream of playing in the NFL and for the lifelong relationships I developed because of that experience."

Diehards Line: The Titans' No. 8 overall pick in 2011 never played an entire NFL season. He'll end his career with just 30 career appearances, including missing nine contests each of the past two seasons. Locker was set to hit the free agency Tuesday, where he would certainly have drawn interest as a backup. Locker will end his career completing 57.5 percent of his passes for 4,967 yards, 27 passing touchdowns and 22 interceptions.
