Bring back a future Hall of Fame player that is still performing near the top of their game for one last ride is always preferable to a team with realistic championship aspirations and chances. When a veteran player is a tremendous leader on and off the field, in addition to being a gold jacket talent, his presence and influence on his teammates, especially the younger generation, is invaluable.
That is exactly the kind of superb veteran leadership that Calais Campbell provides for the Baltimore Ravens and why head coach John Harbaugh was glad that the team was able to re-sign him this offseason.
