Thirteen things about the Broncos entering Sunday’s season finale against Oakland:
1. For Broncos offensive coordinator Rich Scangarello and quarterbacks coach T.C. McCartney, it’s about their right-handed passers having the left foot forward while in the shotgun formation. It represents a major change in Drew Lock’s mechanics.
2. Through four games, Lock is completing 64.8% of his attempts (83 of 128). “What we talk about is, when you’re playing in the pocket and you have a base — feet on the ground, knees bent — we do something different than most people,” Scangarello said.
