Bad ball. Look at the blockers and the defense. 2 on 2 with a WR downfield.
I marked where he would have been at this point if it was a good throw that he doesn't have to adjust 1 handed for.
And the end result, because he had to adjust to a bad ball.
Not trying to crush Carr here with this, but we need to be able to execute screens. This was a touchdown, or at the very least a monster gain if he puts it on him properly. The very next play Carr gets hurt.
