Interesting stat on ESPN:
The Broncos offensive line took a major hit in losing Koppen. Peyton Manning
was sacked eight times in the Broncos first three games last season, all played without Koppen taking a snap. Koppen played 95 percent of the team's snaps the final 13 games of the season, with Manning getting sacked 13 total times in those games.
The Broncos allowed one sack for every 35.8 dropbacks with Koppen on the field last season, compared to one sack for every 18.1 dropbacks with him off the field. Although the Broncos were much better with Koppen on the line, they managed to remain above the league average of 16.7 dropbacks per sack in his absence.
