They were 24th in points while having one of the worst red zone offenses in the NFL...lol. And when you put things in it's actual perspective. they scored less than 2 less points than our top 10 scoring offense last season. Most scoring is done in the red zone and if there was an area that Joe Brady needed to improve it was there. Again, let's look at things in its entirety. The main thing that truly separates the 2020 Panthers from the 2024 Bills is that run game and the red zone. The 2024 Bills were #2 in red zone efficiency this season with 76% of their total TDs (20 passing and 27 rushing) coming in the red area. You are harping on an "elite QB" when in terms of passing the ball, Teddy was better. The 2020 Panthers issue was not being able to get it done in the red zone and that wasn't because of QB. That's something that Joe Brady had to own and as we can see, he has learned.
And they went to a more run-oriented offense because that better suits Josh Allen skillset. As I've said before, Buffalo fans ragged on Lamar Jackson because of his stats during his MVP seasons when Josh Allen is an MVP front runner with similar stats while being less efficient in the pass game. lol
