It varies a lot, especially mid-season. A GM will have much less impact on the roster mid-season than in the off-season.
I agree, Walters should have a short leash. Any of the mafia who return should.
The house from 10 years ago HAS been cleaned. Only Mos and Walters remain. Everybody else is gone. The house from 4-5 years ago is sparse as well. What happened 3+ years ago, has no deciding factor in what happens next year. Shelf lifes are extremely short in sports and even more so in football. 5-10 years is ancient times at the speed football moves.
Dave Ritchie's entire era here was part of 5 and 1/3 seasons. If you line up the competitive parts of the time here for Ritchie, Lapo, and Dunnigan you'd still be short of 10 years. The mafia having been here 10 years doesn't make it more likely that next year will be competitive, it makes it drastically more likely that things will fall apart more and it will end sooner.
yeah, Mueller is not even close to stepping up to a HC job. Realistically no HC is coming in with a bunch of guys from out side his selection as a coach. Maybe 1 or 2 top of the line guys like JY and Marty, but thats it.
I also don't see strevy as a RB coach, and I don't think Biggie would come back this soon to coach.
