I mean a few things. Bills started off slow which is common in games that one team flies a distance. When the Bills started getting rolling they scored two TDs then Interception and then another TD. Punt, fumble and then the long drive to close the game.
This was more about the Chargers Offense controling ToP than it was the Bills Offense. The Bills scored on 4 out of 9 drives. Had 2 turnovers on 3 drives and had 1 punt after their first TD.
