I didn't care for the manner Osweiller acted when he left but let's have an honest discussion:
He did step in and play solid for us, won some tough games.
Manning struggled all year in 2015, his QBR was horrible and was clearly struggling withhis arm strength.
Brock even played well in the game in which he was pulled against the Chargers, The team was dropping passes and fumbling the ball, Kubiak put Manning back in to shake up the team.
Neither Houston or Cleveland have a clue how to develop or even coach a QB. Until that changes, no QB will have any success in either city.
Like it or not, Osweiller will be the better option under center if Trevor goes down.
The Broncos have done everything possible to hand the job over to Paxton Lynch. He clearly has a long long way to go.

Brock took the money. Elway could have signed him earlier for a more realistic amount, but Elway allowed Manning to drag on the inevitable realization that his career was over.

I suggest we put it behind us.
