"It was disappointing because I always played my contracts out," he said. "A seventh-round pick, to make it 10 years in the league is already a blessing, but the first time I got released was then and it was disappointing because I felt like I could have still helped those guys out a lot. I feel like I'm still young, I've got a lot of football left in me.
