TEMPE, Ariz. -- By extending Carson Palmer on Friday, the Arizona Cardinals handed out their second extension in less than four months worth at least $50 million.

Even though two days later his season ended when he tore his ACL in the fourth quarter against St. Louis, the extension from Arizona’s management sent a great message, coach Bruce Arians said.

“Our guys know that Mr. Bidwill is going to take care of you,” Arians said on SiriusXM NFL Radio. “You go out and do the right things and play the way we want you to play and act the way we want you to act, you’ll get rewarded.”

Here are four Cardinals in the final or only year of their contracts that Arizona should extend:

Antonio Cromartie, CB, 30: The way he’s been playing the past few games, Cromartie has proved he may be among the free-agent steals of this year’s class. Remove the Denver game from his stats and Cromartie leads the NFL in cover snaps (number of snaps spent in coverage)) per reception, yards per cover snap and cover snaps per target, according to Pro Football Focus. With 21 tackles and three interceptions through nine games, Cromartie is on pace to finish the year with numbers not seen since his days in San Diego. He’s had more than three picks just once since 2007, when he had 10. He’s established himself as part of one of the league’s best cornerback tandems. Keeping Cromartie will be costly but worth it. 2014 cash value: $3.5 million

Larry Foote, LB, 34: There’s no certainty that Daryl Washington will be back at the beginning of next season because the NFL still hasn’t punished him for pleading guilty to assaulting an ex-girlfriend in 2013. While it’s likely that defensive coordinator Todd Bowles leaves the Cardinals to take a head-coaching job and even though Foote turns 35 in June, he’s been the backbone of this defense, not missing a snap. The flip side is that Foote may want to retire after this season. 2014 cash value: $1.02 million

Dan Williams, NT, 27: Regardless of who’s coaching the defense next year, keeping the heart of the defensive line intact will be critical for Arizona’s success after 2014. Williams has shown his versatility this year, playing outside off the edge when Calais Campbell got hurt. Williams is coming off his rookie contract and he may ask for more than the Cardinals want to give a nose tackle, especially with the success they’ve had with signing cheaper veterans off the street. But Williams has been the center of Arizona’s highly ranked run defense for a reason. 2014 cash value: $1.04 million

Tommy Kelly, DT, 33: He’s been a savior on the defensive line this year after injuries riddled the front seven. With a lot of unknowns surrounding Darnell Dockett's return in 2015, Kelly would be worth a two- or three-year extension with guaranteed money for just one more year. Then the Cardinals can figure out what to do with him. But he’s been productive and likes playing in the Cards’ front seven. Even though Kelly has been part of a rotation, he proved he can play more snaps if needed. 2014 cash value: $955,000.
