Javon Walker's season-ending comments last week about not being a good fit in Denver and possibly playing elsewhere next season were viewed by many as a red flag. The Broncos' receiver in hindsight looks at it more as the yellow variety. "It was frustration coming out," Walker said Tuesday during a radio interview. "It's like playing on the football field and getting a 15-yard personal foul. That's a guy who, at the time, was frustrated. His coach may not like it. But saying something in the media at the time - boom - it's a personal foul." "I apologize. I'm sorry. Let's move on."
