Calais Campbell, a six-time Pro-Bowl defensive lineman, has signed a one-year contract with the Arizona Cardinals to kick off his 18th NFL season. The deal, worth $5.5 million with potential bonuses, reunites Campbell with the team that drafted him in 2008. While he is not expected to start, his experience will be invaluable in mentoring younger players and elevating the team's defensive line, which has seen changes this offseason with new additions like Dalvin Tomlinson and Josh Sweat. Campbell's past season with the Miami Dolphins showcased his ability to lead and produce, recording five sacks and a stellar run stop rate. His return to Arizona may play a pivotal role as the Cardinals aim for playoff contention in the upcoming year.
