Not most games. Last year they scored more than 3 by half 9 times. I don't know why last year matters but here ya go. https://www.pro-football-reference.com/teams/buf/2018/gamelog/
Turnovers are the issue with this team right now. No team can turn the ball over as many times as they have and expect to win. If they clean that up I think they will start scoring more points.
