The first player is obvious and Joe Brady is going to only be as successful as Josh Allen is over the remainder of the year. This will be Allen's third offensive coordinator in his career in the NFL after having Brian Daboll for four seasons.
Ken Dorsey was essentially Allen's pick to replace Daboll when he left to be the head coach of the New York Giants in 2022. Unfortunately, Allen has regressed with Dorsey calling plays and the frustration was very apparent after the game against the Bengals when Allen said "Just the game plan that we had going into it." as he referred to why the team didn't go uptempo.
So what can Joe Brady do to help Josh Allen moving forward? An uptempo offense will certainly help but Allen needs to get back to playing like he did a few years ago. This means, utilizing his legs but it doesn't necessarily mean running for yards.
Joe Brady needs to move the pocket, get Josh Allen on the run and give defenses the idea that Allen could run which will freeze defenders in coverage and should open more passing lanes. It is unfortunately a short week but the focus has to be on Josh Allen and building a game plan that gives him high percentage throws and limits the turnovers.
