The Denver Broncos were in a high-scoring shootout with the Green Bay Packers in Week 15, and I am not sure either team expected the game to go that way. For a large chunk of Sunday afternoon, the usually-stout Broncos' defense was allowing Jordan Love and the Packers' passing game to do what they wanted.
However, as the game went on, Denver's defense really began to buckle down and played extremely well in the second half with multiple key interceptions and some timely sacks. On the flip side, Bo Nix and the offense were honestly humming all afternoon.
