Good points you've made here, although many have contended that Jerry ordinarily doesn't want coaches who would deflect attention away from himself. He did also comment that he mainly wanted Parcells to cement his building of the new stadium. Unfortunately, Jerry just couldn't resist the temptation to bring in TO against Bill's wishes. Bill also confessed that he mainly wanted the job to pay for the divorce settlement of his wife at the time. You just can't make this stuff up!
Additionally, as I recall, Bill Cowher claimed he wouldn't want to work for Jerry due to his meddling ways. So, there are evidently those who would be quite reluctant to take on that somewhat risky plunge, although, MM did just that.
In any event, it's very possible that Dan Quinn would be on tap to replace Mike McCarthy if he fails to impress in 2022. I'm sure we'll see how that goodie develops by the end of the upcoming season. There's always some upcoming drama on tap for the Cowboys -- that's for doggone sure.
