Derek Carr practiced today.

The thing you're leaving out is that CO DID quit on the route, Maybe because he was a decoy. And even if he was a decoy ( see AT Perry on the INT play last game ) there is a chance that you may get open.
You do know he did his job, right? His job was to clear that space out for Taysom. Tape shows it was done and CGM, in his tweet, confirmed the same.

Here is the crazy thing; if you say that Olave quit on his route and that's why he threw it away, you will have acknowledge that on that play, Carr did a worse job, as he completely whiffed on 2 of his 3 reads, even though Taysom (his first read) was open. Matter of fact, if he didn't discuss with Olave that he would throw him the ball if he breaks free, then he has just gone renegade with that play. If you really begin the peel the layers on that play, Carr looks to be the bigger offender. But that was weeks ago.
