Carr and completed air yards—a few plays from the Bears game

The theme to all of these is the right play was called to beat the D, but the OL got beat. There were open receiver in all the plays.

As the OP stated, when the OL provided a clean pocket, Carr locked onto Thomas instead of the open receivers. CGM is no longer an elite receiver.
Thats not what I see. I see random plays where there was no completion and in retrospect we are yet again judging Carr on a supposedly "missed opportunity", but you can pull these same kind of 4-6 second clips on Patrick Mahomes on any of his incompletions.

The defense is flowing toward the ball so what you think is an open receiver is really just the defense moving toward the play.
