2.) Transition at the right time on offense
From Week 5 to Week 10, the offense for Buffalo could not get a rhythm going which made them get off to a slow start against multiple opponents and it cost them some games as well.
In Week 6 against the New York Giants, the Bills would not see their first touchdown of the game until the fourth quarter in which the Bills ended up winning 14-9 because Giants’ quarterback Tyrod Taylor could not convert on the goal line to tight end Darren Waller. In Week 7 against the New England Patriots, the offense would not help take the lead from the Patriots until late in the game (just for Mac Jones to walk down the field to win the game). Then against teams like the Bengals and Broncos, the offense under Ken Dorsey was not performing at the elite level it once was.
Then came in Joe Brady, who took over for a fired Ken Dorsey and the offense for Buffalo went on a hot streak on offense, scoring no less than 20 points and scoring over 30 points in three of the last 5 remaining games. Brady was able to get the run game going with James Cook and get guys like Dalton Kincaid and Khalil Shakir involved more in the passing game. While the offense did not perform at this big elite level, they were not lightly taken either from the opposing defenses that they faced.
