But Jones' production wasn't the only reason the move appealed to Arizona, according to Bleacher Report's Jason Cole, who notes the team is hoping to get more production from 3-4 end Calais Campbell. Per Cole, Arizona hopes that the presence of a top pass-rusher will divert more double-teams away from Campbell, who had a down year (by his standards) with five sacks in 16 games in 2015. In each of the previous four seasons, Campbell averaged at least a half sack per game despite battling injuries.
Also noteworthy from Cole is that the Cardinals don't plan on extending Jones' expiring contract until after the 2016 season, when Campbell's $15.25 million cap hit comes off the books. That makes sense, as Arizona now has very little space to work with in 2016, but it's not clear if that means the team expects to keep Campbell around beyond next season.
The Cardinals have committed less than $100 million toward 2017 so far, 10th-lowest in the league, but keeping both Campbell and Jones off the free-agent market could be difficult. As a talented young edge rusher, Jones should be a candidate for the franchise tag, especially when considering the huge contract the New York Giants gave Olivier Vernon and the mammoth deal Denver Broncos linebacker Von Miller should command. But that would make Campbell, who will turn 30 in September, available to other teams if the Cardinals couldn't reach an agreement before free agency.
Plenty can change between now and then, of course, but it's possible the acquisition of Jones could lead to the departure of Campbell.
