With these answers, keep in mind my eyes are on Super Bowls and Championship games. Making the playoffs is fun, but... I want to be one of the last 4 teams standing as consistently as possible.
What makes Brady special to me? - I recognize that franchise QB's are essential for repeat runs deep into the playoffs. In fact, if you look at the teams most likely to repeatedly making Championship appearances, the two things they have in common is a great head coach and a franchise QB. Brady, has a knack for QB's having their best year under him going back to college years. Even in Carolina, Bridgewater was having a career year. Theres one single season that didn't work well and that was with Sam Darnold, who mind you, also just cost the Vikings with his awful play with Kevin O'Connell at the helm and we know how good Kevin O'Connell is.
Burrow credits his growth to Brady. Bridgwater has a career year under him. Darnold tanks and was forced by Matt Rhule, and Brady then elevates Josh Allen to MVP and Allen very clearly wants to keep him in Buffalo. On top of that, no matter what defense Brady's offenses are up against, he finds ways for his offense to put up points. Usually a lot.
This gives reason to the idea that if Brady is head coach, at worst we will be similar to the 08 Saints. Putting up points but can't play defense. Given his success of elevating QB's, it also gives reason that he stands a decent shot at helping the franchise find a franchise QB, and grooming him even if Brady doesn't work out as HC. The next one in theory will have a franchise QB to open up our potential searches for coaches. Is that a risk to not work out? Absolutely. But a franchise QB is worth it imo.
Having a guy who's never coached before tends to come with a big drive. So when I see a coach who has elevated offenses greatly wherever hes been and now wants a head coaching job, the odds seem in favor of success of at least being highly competitive.
Now, my question of wanting a new first time head coach over a guy who's won a SuperBowl. No. The NFL changes drastically, usually around every 5-7 years. The game keeps evolving. For that reason, I like to look back the past 5-7 years. McCarthy has no won a superbowl in around 15 years. That's double the lifespan of evolution in the NFL. So to me, I immediately throw out everything going back that far. The most impressive times for someone like McCarthy was around 2010. After 2014, Green Bay started as a struggling team, especially in post-seasons. Now some people want to blame that on Rodgers. But we saw it in Dallas also. 1-3 in post-seasons.
There are currently 4 teams who need head coaches. We're the only ones considering McCarthy, while Brady is now supposedly being pursued by the Jags after Coen resigning with Tampa. Why is that? If McCarthy is so proven don't you think at least 4 out of the 7 teams who needed a head coach would look to him? Only none did except Saints and Bears. What do the two have in common? Their last head coaching decisions were absolutely atrocious. So ya, I'm basically saying I don't trust Loomis in this process. I find it extremely unlikely that anyone thinking Dennis Allen as a head coach was a good idea.
All of this makes Brady the obvious choice for me. And that's not even getting into when front office officials for Green Bay criticized what his play calling and game planning has turned into which raises my concern for MM.
