I think people get same plays and same offense confused. Obviously they are going to run the plays they think minimize the weaknesses of their QB and maximize his strengths. They are def running the same offense, for some reason zappe seems to have more of the offensive playbook open to him right now. But yes, they are running more plays with zappe that require him to turn his back to the defense and then quickly diagnose it and move well in the pocket.
Jones isn't doing that well now, which is why I think they are keeping him in shotgun, to give him more time to read things and scramble if need be. They are giving up a huge advantage in freezing the LB's because they don't have faith Mac is running this offense well. And to be fair to the coaches, he wasn't running the JMD offense well for the last quarter of 2021 season either. Which means defensive coordinators probably already have Mac figured out and he's not adapting.
