Lol, because it is an absurd question that would require someone to build an actual career in general management of a football team. You don’t need a full account of every detail of the opinion for it to be valid. The bulk of us can see that many other squads have moved on from QB’s even when lots of money and personnel/planning have been used to build around that QB (even when the QB is still on the books for lots of money).
Plenty of teams move on from cores of teams when postseason success does not happen, even though regular season success is dependable with that core.
Here’s a handful of ideas (assuming no NFCCG game appearance or dreadful performances from Dak in the postseason). You keep Dak next season obviously because of cap implications, but eat the cap hit without extending the contract. Trade Tyron Smith, but if not possible-cut him and save $9.6 million next year. Cut Ezekiel Elliott and save a little less than $5 million. Cut Jourdan Lewis and save $5 million. All indications are that the 2023 cap will be well over $220 million. These moves and possibly extending Lawrence for another couple seasons with some more guaranteed money would put the Cowboys under the cap by at least $28M and possibly $35M or more.
Go after Da’Ron Payne with a good sized contract for a nose tackle with a bit of pass rush (maybe Tomlinson if that falls through). Maybe 3 years of guaranteed backloaded 5 year contract with $30-40M guaranteed. Look to re-sign Tony Pollard, but no more than Payne and probably only $30M guaranteed. Look to re-sign Fowler, Donovan Wilson, Jonathan Hankins, Jason Peters, Noah Brown, Conner McGovern to small or sub mid-tier short contracts. Not sure that Cooper Rush would stay as a backup and not sure his market value (may be too expensive to re-sign, nothing more than $4M per season).
The biggest move I would attempt is trading for Laremy Tunsil. Offer this year’s first and next year’s 3rd (but I would be willing to go with a 2nd rounder) and maybe a 5th rounder this year too and maybe a 4th rounder next year. Sign him to a major contract extension (5 years and backloaded).
Target cornerback, linebacker, center, interior defensive line and edge rushers in the draft.
There you go. A semi-plausible scenario. If Dak plays terrible in the postseason-you move on regardless (look to move up in the draft with future picks and maybe a player-not in 2023 though). If he looks very good AND the Cowboys make it to the NFCCG, you can look into an extension.
