ENGLEWOOD, Colo. -- The Broncos are 4-0, and some numbers help explain why they've reached that mark for the third time in the last four seasons and the ninth time in franchise history.
We start with a number that shows why Trevor Siemian will return to the lineup once he is ready following the sprained left shoulder he suffered Sunday against the Tampa Bay Buccaneers:
1. 99.6
That's Siemian's quarterback rating through four games, which places him ninth among the 33 passers with at least 50 attempts this season.
