At 38 years old, Calais Campbell enters Year 18 in the NFL, ready to pass on all that knowledge he's compiled.
Every veteran player approaches mentoring in different ways. Campbell said it's an "honor" to show young players the ropes, knowing it can make the team better.
"I enjoy passing knowledge," Campbell said last week, via the team's official website. "I feel there is no point for me to die with all this knowledge, to the graveyard at the end of my career. I have to share with as many people as possible, especially people that are going to help us win ballgames.
"If I help them to a level that's better than me, then the team is better and I will find my role and make it work."
Campbell is back in Arizona, where he first learned to be a pro.
The defensive end spent the first nine seasons of his career with the Cards, growing from second-round pick into a star Pro Bowler. He spent the past eight seasons bouncing between Jacksonville, Baltimore, Atlanta and Miami.
"This is where I learned how to be an NFL football player," he said of Arizona.
Campbell is at that stage of his career where he's almost as valuable as an extension of the coaching staff, able to relay messages and give young players tips on how to improve. The six-time Pro Bowler noted that he's probably only able to play about 30-35 snaps a game at full speed.
