Justin Fields traded to the Steelers for a conditional 6th round pick

Find where I said that. I might have missed a game or 2 here but I watched the replays the next day.
Also, Carr improved because Sneaky Pete had to simplify the offense for him. We had to do things like increase play-action and motion. So of course you will see improvement. Winston on had a limited off season and 3 games to run Pete's offense and we didn't see any modification throughout the season to make it better with Dalton. So again, same energy...
Play action and motion is not simplifying the offense. It’s something all NFL teams with an offense worth anything know how to do and do it well.
