Bills after November 1st:
2022: 7-2
2021: 6-4
2020: 8-1
This team has been getting white hot in late November with long win streaks.
14-2 in December and January (regular season) since 2020.
Except, outside CMC, I cannot think of a single trade deadline deal that helped out the team who acquired the player in that same season. Seems like actual on-field impact is minimal.
