i think they realized that they cant go the way of slippin jimmy as some kind of master con man because breaking bad saul was slick, but wasnt a fucking boss. he could slip and slide his way around the cops and lower tier criminals, but ultimately he was just some better than average ambulance chaser.
when you look at it, his watch con and dinner cons he played with kim was really basic conning, jimmy can do those because he is an excellent salesman, but no mastermind of the long game. Darren Brown he is not.
