The San Francisco 49ers are desperate for help on the defensive line. They have already addressed this in a minor trade with the New England Patriots, but now they should set their sights on Arizona Cardinals veteran Calais Campbell.
The Keion White trade with New England gives the Niners some needed depth on the edge, but the team still needs to find a way to put more pressure on the quarterback. Campbell is an interior defensive lineman rather than an edge rusher, but he would still help the team have some sort of pass rush.
