This team probably got .3 better in FA. At this point, all Mickey is telling me is that they truly do think the '24 season was a fluke and are heavily banking on a new coaching staff to get more out of what they mostly have already. Even with Reid as an upgrade over Harris, you're mostly running this back with underperforming players on a defense that was mostly healthy last year.
They are keeping a lot of players, but they have overhauled the coaching staff who will overhaul the offensive and defensive playbook and playcalling. They are not "running it back," just because they are keeping a lot of the players.
