Head coach Gary Kubiak doesn't need to making sweeping changes to his passing game yet.

Benching Peyton Manning is extreme. He might find it easier to install a "Brock Osweiler" package -- a handful of plays tailor-made for the Broncos' backup passer.

Manning currently sports a worse passer rating than Jameis Winston. He's on pace to throw fewer than 20 touchdowns for the first time in his storied 18-year career.

It's not easy to simply pull the plug on a future Hall of Famer. A call for Osweiler would be in line-step with what Kubiak planned to do from Day 1.

Then, Kubiak could dig into more deeper passing elements of his playbook, rest his soon-to-be 40 year old starter, and evaluate Osweiler in meaningful game situations.

The latter point is of upmost importance. Osweiler hits the free-agent market this spring and the Broncos don't know if he's a rightful heir.

There's only one way to find out. Usher in the Osweiler era, slowly but surely.
