You’re missing the point. You can hire 20 guys to be above the GM to hold him/them accountable. But in the end, George is still at the top, making that initial decision.
All your scenario does it make more guys for George to decide to fire or not.
In that situation, I believe that the Bears are still cheap.
Having George or any of the other clueless McCaskeys, the Bears organization needs several layers of football experience as a form of stability and as checks and balances.
Their old way was to have a GM who talked to Ted Phillips who talked to George who talked to "the board" which is basically his family. Every single layer is filled with football idiocy, not intelligence.
Their new 2022 way is to have a GM talk directly to George who will talk to "the board" and you get one less layer of football idiocy.
Too much is put on a GM's plate and there is zero support for him. Pace had to get free agents (done poorly), draft players (bad but better than his free agent work), renovate Halas Hall (seems to have done a fine job), deal with contracts (seems to have done poorly) and countless other jobs.
Ted was (and George is) too football stupid to be of any help yet they were the only sounding board for Pace and will be the only sounding boards for the next GM.
George and "the board" refuse to add a position of president of football operations (making Ted President of Counting Beans) which could make an honest evaluation of the present state of the Bears and to evaluate and advice the GM. They probably refuse because that would decrease the paychecks that the McCaskey clan gets.
It took decades for the Bears to change the cheap ways of George Halas dealing with coaching and players. Now it is time for the McCaskeys to change their cheap ways when it comes to creating a strong executive branch of the Bears.
Weeks ago, I dreamed of the Bears hiring Dodds or Smith as the GM (an upgrade of position for Dodds) and Morocco Brown as Assistant GM (also an upgrade in position so maybe the Colts couldn't block it) with the promise that in 2 years, if they were successful, Dodds or Smith would become President of Football Operations and Morocco would become GM.
This would have given the Bears the needed football experience in the building, isolating George from making any football decisions, seeing that he is just a fan.
Moreover; seeing that the McCaskey kids are part of the football business, they need to be trained from a young age in the workings of football.
Decades ago, all the McCaskeys should have gone to John Madden to be taught the game of football (he actually had a course on that very matter), should have paid Bill Polian, Ron Wolf or Ernie Accorsi (I don't think that either one has a course but money talks) to teach them the business being an executive in the NFL.
Finally, the McCaskeys should have, from a young age, served internships in every single facet of the Bears from equipment manager, scouting, to an internship with a GM, creating relationships with the players while learning the business and learning humility.
George's yearly pressor clearly shows that he does not have a clue about the business, doesn't care about former players nor does he have a sense of humility.
