John Elway knows the value of a quarterback in his late 30s changing from a pass-centric to a run-heavy offense. It helped him win two Super Bowls at a time when it appeared he might end his career without one. This mindset is part of why the Denver Broncos, with Elway making their personnel decisions, want to make significant changes to their offense.

The wild card here is QB Peyton Manning. He has always run a pass-first system and could be reticent to embrace another approach this late in his career. The hesitation would be understandable, but a closer look at the Broncos' scheme and personnel offers a host of reasons why a change in philosophy could be just what Denver needs to win the Super Bowl.
