Campbell anchored the Cardinals' defensive line in 2011.
There may not have been a bigger move on the defensive side of the ball than signing Calais Campbell to a five-year, $55 million contract, with $31 million guaranteed.
Campbell, the 6'8" defensive end, recorded 51 solo tackles, 22 assisted tackles, eight sacks and three blocked field goals in 2011.
His best effort was the Week 3 game at Seattle when he recorded 10.5 tackles and picked up 2.5 sacks in a 13-10 loss.
Campbell would have been one of the most sought-after free agents had the Cardinals not put their franchise tag on him. A defensive end of his size who can get to quarterback would have been a prime target of several teams in free agency.
With the Cardinals keeping him, Campbell continues to be paired with Darnell Dockett, keeping one of the best defensive lines in the league intact.
