Something to keep in mind. Elite QB's throughout their career for the most part have struggled to win in Denver. Brady is 2-7 against the Broncos in Mile High. Big Ben is 2-4. Drew Brees is 0-5. Rodgers is 0-1. Not an easy environment to come and play in and the altitude does seem to effect QB's quite a bit as the ball does seem to float a bit more on them. Wouldn't surprise me to see Cam miss long on a couple of deep passes that in Carolina might have been a completion.
Broncos also All-time best record for the AFC in season openers being 36-19-1.
More importantly.....what about rookie QB's in Denver?
