My initial idea was to look at Andy Dalton’s stats in Chicago compared to his previous seasons. Dalton has been on three different teams over the last three years – Cincinnati in 2019, Dallas in 2020, and Chicago in 2021 – so if his performance took a drastic drop in 2021 compared to the previous stops, that would be supporting evidence for the theory that Fields was hurt by the offense around him.
The table below examines Dalton’s efficiency (blue) and playing style (orange) across his last three seasons. Deep throw % is from Pro Football Reference’s Game Play Finder, while all other playing style stats are from Next Gen Stats.
