The impending free agent told USA Today's Tom Pelissero that his No. 1 goal is winning a Super Bowl, even if takes years to do so.
"I love the game. I'm not going to stop 'til I'm dead," Tillman said. "Obviously, I can't play until I'm like 50 or 60. But I just want to keep going. I'm feeling good. I just have unfinished business. I want a championship. I think that's my main reason (to keep playing): I'm hungry for a championship."
Tillman, turning 34 next week, added that he's 80 percent healthy and hopes to be fully recovered from his second torn triceps injury by the time free agency opens March 10.
Tillman told Pelissero that he has only had a "hi and bye" interaction with new general manager Ryan Pace and coach John Fox.
He's not ruling out a return to Chicago, but is open to all 32 teams now that the window is closing on his career.
