Disagree. During the entirety of the regular season it was absolutely a step back compared with the 2020 regular season. He was a legit MVP candidate in 2020 and received votes. He dropped off in nearly every metric in 2021 and, unsurprisingly, the Bills regular season record was significantly worse than 2020.
2020 - 4,544 yrds, 7.9avg, 69.2% completion, 37 td, 10 int, 76.6 QBR, 107.2 RT
2021- 4,407 yrds, 6.8avg, 63.3% completion, 36 td, 15 int, 60.6 QBR, 92.2 RT
The numbers don't lie.
Amazing postseason performance and something to build on. That being said, a better regular season performance (obviously not just him), and this team is home for the entirety of the playoffs.
