Yaaas Broncos!
It's important to remember that Keenum numbers are slightly inflated by Diggs and Thielen, who are not only great route runners but are also two of the best at contested catches.
He also had much more protection to be fair, look at the comparatives for number of sacks and yards lost to sacks, Keenum obviously had more time available to throw.
That said, poor protection or not Cousins throws too many picks.
