Barkley had a near identical performance. He just wasn’t given the same number of attempts.
He also threw a 1 yard pass on 3rd and 10 (but was bailed out by a Broncos penalty).
And a 5 yard pass in the middle of the field with only 1 timeout and only 30 seconds left in the half.
And on the Crowder play you mentioned above, he needlessly backpedaled into the pocket, right into the defensive ends - if it was the regular season, it likely would have been a sack.
And then Barkley came in and only had 1 incompletion.
