Two seasons. Two seasons, and they bailed on the greatest coach in the history of the game in favor of a coach that has ZERO head coaching experience and a quarterback that has proven, beyond a shadow of a doubt, that he does not have the strength of character to be an elite quarterback in the NFL. The Dolphins gave Shula EIGHT years to turn it around. Look at Tomlin. I think you sit down with him, O'Brien, and say look, we're done with Mac Jones, let's plan the future right now. You get to draft, you get to cut the players down to 55, but we're moving in another direction than Mac Jones whether you like it or not.
Above was your original post but your later post did a better job of adding context to your thoughts:
1) I am well aware of you what you didn't say. All I was saying was that there have been plenty of successful first year coaches but I disagree with you about replacing a coach and "knowing" that the replacement will do better. How can any owner "know" they are going to do better? And if anything there is no guarantee that a that BB will have success in the future. Just look at Tom Landry.
Well, "know", "think". My point is, Kraft can't POSSIBLY be in the headspace that "yeah, Bill's better, I'll do better with him, but we're going to give Jerrod a shot". By WHATEVER metric Kraft is using, Kraft feels he's better with Mayo than Belichick, and other than "Mayo might be coaching in 15 years, and Belichick will almost certainly not", I can't, myself, figure out what that metric is.
2) If you are saying that Shula or Tomlin were given years to turn things around after their initial success then I agree with you. The cardinal sin of an owner is staying with the same coach too long but a coach is only as good as his QB.
I generally don't disagree with that point, but "only as good as his QB" is dynamic, because a QB is only as good as his coach. Who are the greatest QBs of all time? Other than MAYBE Payton Manning, every one of them played for not just a very very good coach, but a LEGENDARY coach.
3) I'm sure the Pats are done with Mac Brown but I still think BB ruined him. I mean it was his "genius" that put a DC as an OC with no experience. Also, after that rookie season with Mac, someone on this board said "Patriots in the Super Bowl in 3 years, book it". Josh Mcdaniels was the OC at the time and I think the next season to the Raiders? After that, Mac's production fell way off. With better coaching, I think Mac can be a serviceable QB in this league.
I may have been that guy. I was Team Mac from the get-go; had he had a backbone, had he been better able to handle the pressure, I think he COULD have been at least as good as Jim Plunkett or Bob Greise, or Eli Manning (QBs with two or more Super Bowl wins).
I think the OC thing is overblown. I'm not a fan of Patricia, myself, but he was a head coach. He's a football guy. I think it was within his wheelhouse to be the OC. He started out on that side of the ball (and technically speaking, JMD started out on the defensive side of the ball). Belichick is known as a defensive wizard but even HE was a tight end in college and his first couple jobs were on that side of the ball. I would have preferred JMD stay for the first couple years of Mac's career, but no one cares what I prefer. The reality is what the reality is. At the end of the day he has to perform. We're not talking about kids, we're talking about grown men.
People seem to rely on a head coach's past success and but their past success is no guarantee of future success. BB wants to run the whole show and owners are shying away from that. I understand that Arthur Blank wanted BB as the coach but not GM.
And that's fair. I can see that; many - most? - teams want to run by committee for continuity. That's Bill's call whether he wants to relinquish that or not, and if he doesn't it's his call.
