The issue is scarcity of cap space and not a ton of moves to get cap space easier.
I want to keep Golden, Reddick, and Peterson. I think Golden isn't a top pass rusher, but he's a solid rotation guy. I think Reddick can be a KGB like pass rusher who is primarily a 3rd down kind of guy. Peterson isn't a shutdown guy, but he's still better than 70% of the leagues corners and guys like that still get paid.
Jones is getting old. He has one more year left on his contract and is coming back of a season ending injury. His name should still have some value, and a contending team may view him as the final piece to get them over the top. I'm a CJ fan, but at the end of the day, is usually a passable run defender and slow twitch pass rusher. I'd wager the majority of his sacks as a Cardinal come in the 3-4 second range (coverage sack), he rarely beats a guy and gets one of those 1-2 second sacks.
One of Keim's biggest issues as a GM is that he tends to wait until a player is gone to address roster holes, while you routinely watch the good GMs draft a guy a year early to take the place of the expensive veteran you know you aren't going to resign. I don't want to keep CJ at the end of this contract; I just don't think his game will age well once he gets even slower.
Colts, Jets and Jaguars are about your market for Chandler Jones. Also, with Kyler Murray on a rookie deal, I am prepared to pay Chandler Jones one year too much. I think it is easier to just rework Chandler's deal. He will want the upfront money and we don't need another Calias Campbell situation.
If you take out the Giants game, Reddick has 5 sacks. I would rather let him walk than risk paying him 15 mil on a multi year deal. 4yrs 40 mil, I can stomach that.
Golden would be nice, but he isn't much different from Kennard. If Golden wants to look for 8 mil, let him as you still have Kennard on the roster.
Ideally, you extend Jones (dropping him cap hit from 20 to 10 which is his bonus spread), sign Golden for 4, and transition tag Reddick if he won't take an 8 mil per year deal. You draft an EDGE player in round 1 like Oweh, Ossai, or Ajulari and see who earns the reps. This way, in 2022, you let Reddick walk, still have Golden, Jones and your first round pick. Honestly, this also might be the EDGE class to draft one in round 1 and 3 (or trade back in 3 for an additional 4).
