Say whatever you will about the quarterback play from a season ago; Peyton Manning was old, his arm was weak, he couldn’t make the throws; while there is certainly some truth to this, the fact of the matter was his offensive line was downright terrible. When I watch film from 2012 and 2013, the differences between Manning then, and Manning in 2015 weren’t that large. What was different is the amount of time Peyton had to throw, and the lanes that were opened up for the likes of Willis Mcgahee and Knowshon Moreno. In 2015, the Broncos offensive line was mangled with injuries, and was highly inconsistent.
