When the Broncos let their two-possession lead over the Chargers slip away, losing another close game as the clock expired in Los Angeles during Week 3, the Broncos had moved to two games behind the Chargers in the divisional standings. Since then, the Broncos are 2-0, and the Chargers haven't won a game. Arguably more importantly, the Chargers lost on the road to the Giants while the Broncos were able to beat the defending champions in their stadium.
After the Broncos were able to finish off their incredible victory, it felt as though all options were back on the table for their season, including winning an AFC West title.
