once Lamar came in we beat the Bengals 24-21, Raiders 34-17, Falcons 26-16, lost to the Chiefs in a nail biter 27-24, beat bucs 20-12, Chargers 22-10, Browns 26-24, lost to the Chargers 23-17.Also they were not tearing up the league in 2018. That was his rookie year and it was just kind of close narrow wins. Tearing up the league was the year after and that loss was to the Titans. Even that though you can kinda ignore because the team was suddenly ahead of schedule which triggered an increase in expectations.
There were a couple close wins, but I think you are remembering incorrectly.
