I believe that how quickly Josh McDaniels got to Mac Jones after the game speaks v-o-l-u-m-e-s about what is going on "behind the curtain" in New England. More than "Mac Jones regressing" it seems like the foundation underneath him has regressed massively. I can't begin to imagine how adrift Mac must feel without [competent] professional[NFL worthy] position and offense coaching.
FWIW... Those suites do look sweet. (Welcome to Las Vegas! ...Right? LOL!)
