Best way to lose your team is keep the best player on the bench. Let Glennon go out there and lay an egg week after week, while Mitch stays on the bench, you'll lose this entire team. They don't give a damn about sitting and waiting a year for the rookie to "learn." If Mitch gives the team the best chance to win and they don't play him, the whole team will give up.
Look at the culture of this franchise over the last two decades. A whole bunch of losing with some wins spread throughout. It's a losing game when you keep your best chance of winning on the bench. This team needs a change of culture, not to let their best QB sit at 3rd string all year for absolutely nothing. If you think the rest of the players are worried about Mitch sitting for a year so he can be "ready," you're fooling yourself. A few more wins than the previous is a huge deal. You talk about winning a couple more games as pointless. It's not pointless to the players. Good luck to Fox if he sticks with the worse qb. His players will ignore everything says from then on.
