Agree it's the background that informs the sentiment.
He also is plainly skeptical of the Broncos ability to contend. He sounds a bit despondent about it, like he will do everything within his control but it's out of his hands and common sense prevails.
Part of the frustration is how uncompetitive the Broncos are, and Keenum is central in that. Kelly in preseason showed enough to give him a run at starter.
But he botched it.
Sure, the Broncos could have overlooked it. But they didn't. There are good reasons for that. It's on Kelly. It doesn't get that far if he's a good teammate, he'd have his boys lock him up before it escalated.
My problem is that some of us seem to refuse to acknowledge fault.
