This much is true--he plays as much one-gap as 0-tech/two-gap in base D, maybe more, and in the 75 - 80% of snaps in nickel/dime he's off the nose, though I think you have to look pretty hard to find his 5-tech snaps.
"Nose tackle" has increasingly become an anachroistic term with the general decline in base D frequency and teams playing a variety of fronts. For the nickel/dime snaps, this is largely true all over the league for any "nose tackle" who is a 3-down player. The differentiator is how far and how often a player sets outside 3-tech, playing against the OT talents in this league which in Clark's case is not very often. The overthecap categories are more apt where 3-4 DTs (lower paid) are differentiated from 3-4 DEs (higher paid), with Clark in the former category.
What is also true is the Packers have a $175 mil in cap commitments for 2021 for 46 players compared to $180 mil for the current top 46, or $182 mil once the top 3 picks in this last draft are signed. Of course those same 2020 draftees will eat into the 2021 cap as well at higher amounts than in 2020.
The 46 players under contract for 2021 do not include unrestricted free agents Clark, Bakhtiari, Jones, J. Williams, Linsley and King, along with the lesser lights Funchess, Taylor, Lewis and Irvin. That's a lot of talent and/or snaps, depth and roles in this group with a scant $5 mil in reduced cap cost if
none of those players were re-signed.
This would be problematic in what has become a routine $10 mil bump in the cap each season. The prospect for any bump remains in doubt.
Further, there are no obvious candidates at this juncture to be cut after the season for cap savings in 2021. The possibilities for some moderate cap savings are all guys who are projected 2020 starters, so those guys going out the door adds more names to be replaced in the 2020 vs. 2021 apples to oranges comparison.
Cap space currently stands at around $11 mil for the top 51. By the time the top 3 draft picks, players 52 and 53 are subtracted, and the PS is paid, that amount drops to around $6 mil less any PUP/IR replacement costs as we go along. We should still figure on picking up $4 mil in cap with Taylor's release especially now given the Day 3 draft picks, Runyan in particular. That's helpful but not exactly a game changer. From the geginning they were going to capture Linsley's $8.5 mil cap savings and that looks more to be the case now than then, especially after paying him $850,000 in roster and workout bonues. (The NFL is playing workout bonuses for "virtual workouts".)
This year, as happens with frequency, what seems like a lot of cap space dwindles away in backing and filling roster holes without securing an impact player. Bulaga and Martinez represented a light FA group with their replacements part of that back-and-fill. Next year not so much.
So, when it comes to Clark, it is not a matter of "just pay the man". It's also who you don't pay in the process. Is he worth more than these guys:

That's fair. Are you going to put him in the top 10 among these guys:
https://overthecap.com/position/4-3-defensive-tackle/ plus
https://overthecap.com/position/3-4-defensive-end/
That's a dubious proposition. Good player, not a great player.
Maybe the plan is to part with Rodgers after this season, capture his $5 mil in cap savings, start over with the athletic Love scrambling around behind a rebuilt O-Line when he's not throwing timing passes, while running the ball a lot with Dillon and Ervin (or next year's draft pick) for change of pace. In that case go ahead and pay Clark his $15+ mil. You better not win the Super Bowl in 2020, however. It would be hard to dump Rodgers after that.
