OMG please just NO! Maybe get rid of Zo, put Hoyer in his place.
But I really want to see the games play out with the back of the roster guys fighting for their professional lives.
The very argument you make in favor of joint practices over games is to me an argument against that. The controlled scripted nature of practices means there’s not the chance for guys to rise to the occasion when the unexpected happens. We’d never get to see Morton punting, for example. Or Amari Gainer Quintayvious Hutchins forcing a game clinching fumble. And Kyle Williams taking a 68 yard TD to the house would not stand out, it would be lost in the dozen or so similar plays made by AJ and Doubs and Boutte et al. Look back at the joint practices and could how many such plays were reported. They are different kinds of sessions, and the gameplay is still needed. Plus it gets the coaching staff a chance to practice game situations, challenges, substitutions, decisions under real time pressure not simulated.
Preseason games provide situational elements that joint practices do not. They give players on the roster bubble a chance to show how they respond to live game anction. Eliminating them would detract from the overall quality of the NFL season.
