He played in one game, the season-opener against the Chicago Bears, before being waived and signed to the practice squad.
Waddell was named second-team All-Gateway Conference as a senior for the Leathernecks.
He was named the team's Newcomer of the Year in 2000 after transferring from Texas A&M. At Dodge City Community College, Waddell was named a first-team junior college All-American in 1998.
Last summer, Waddell was featured on HBO's "Hard Knocks: Training camp with the Baltimore Ravens." Here's a transcript of his interview with Ravens Insider:
Ravens Insider: "How has your life been changed by being on Hard Knocks? What kind of impression do you think you made on people?"
Waddell: "Everyone still recognizes me from last year. People expect more from me. I think people saw a young man who had a dream and wanted to make the Super Bowl champions' final roster. "I'm still an average guy, down to earth. Nothing has changed about me."
Ravens Insider: "What do you expect from yourself from a football standpoint?"
Waddell: "Now that I've had the experience of the practice squad, I have to play a lot better than I did last year."
Ravens Insider: "Is your speed as a former track standout your best attribute?"
Waddell: "Yeah, if you don't have speed as a football player you have to make up for it in some other area, and that's tough to do. If you have speed and skills, then you shouldn't have too many problems."
Ravens Insider: "What have you learned from your new position coach, Donnie Henderson?"
Waddell: "He's taught me some different techniques. He does a good job of explaining things. He's a good coach. He'll go far."
Ravens Insider: "What's the challenge for you now that you're back on the team for a second year?"
Waddell: "My challenge is making the final 53-man roster, making it and staying on there. I'm looking at it like I'm a rookie all over again."
Ravens Insider: "What motivates you to prove yourself everyday?"
Waddell: "I wake up everyday looking to prove something because I haven't shown I belong in this league like a Peter Boulware or a Ray Lewis. I have a lot of work to do as far as establishing myself. That's why I wake up every morning and try to bust my butt.
"Like they said, the NFL stands for Not For Long."
