Coaching Josh Allen is quite different than coaching Allen and the other 51 men suited up each Sunday.

As the Bills ready for their first season under new coach Joe Brady, who was promoted from offensive coordinator this offseason, there is some concern about how that power dynamic could play out after the quarterback’s influence reportedly led to some “frustration” among the former staff.

“They’re going to be good. Josh Allen’s going to make them good. But within that, like the greatness or is it too much of a good thing when your play-caller goes from kind of being your confidante and maybe a little more of a friend than the head coach could be, to now going into that head coaching job. I think that is an interesting transition to make, when clearly before with (Bills ex-coach) Sean McDermott, he was in charge, also a defensive pedigree,” The Athletic’s Mike Sando said on “D.A. Live” on Monday.

“I’m sure he went along with a lot of stuff Josh Allen wanted to do, but there was a little bit more of a check and balance there, I think. And so now: What does it mean? Is Josh Allen more empowered?

“I’ve heard whispers and people complaining a little bit in the league about the fact Josh Allen gets to kind of do the pass protections how he wants them, I think that’s been a little bit of a source of frustration on the staff, at times, in the past. Is that a good or a bad thing, if that’s enabled more? Those would be the concerns. Not so much Josh Allen, I think we know he’s going to be a star. Just as you try to get over the top, are these fine-tune changes good? Maybe not quite as good.”

The Bills opted for a different path this offseason after nine seasons with McDermott, including seven straight years falling short in the postseason.

McDermott brought a defensive-minded approach to the role, and the Bills opted for the offensive-minded Brady after he served in multiple roles fro the franchise dating to 2022.

Brady worked as both the quarterbacks coach and offensive coordinator, allowing him plenty of one-on-one time with Allen.

The two are close due to their time together, with The Athletic reporting that the quarterback was part of Allen’s interview for the position.

The key for Brady will be ensuring that friendship doesn’t became a problem for the team or for the other players to feel there is preferential treatment beyond the breaks an ex-MVP will receiver.

It’s not unusual for certain star players — like Allen — to have the ability to change plays as they see, with certain coaches being more flexible.

Brady, 36, may be more open to allowing Allen to run the offense the way he sees fit, especially as a first-time head coach.

“I’ve said this 100 times, and you’re gonna hear me another 100 times saying it. I want Josh Allen to get everything he deserves in this life, in this career,” Brady said in March after being promoted. “He puts so much into this game, and that all I want is for him to be holding what he deserves.”

The Bills are hoping that Brady’s tutelage can potentially bring out the best in Allen, the 2024 MVP who has yet to break through in the AFC.

Buffalo’s five-year run atop the division ended last year, and the team fell to the Broncos in overtime in the AFC Divisional Round.
