Tomlin has always been slow to react/respond/adjust. Whether it is during the game, during the week, during the bye or whatever. Tomlin has some strengths (no, I don't want to debate Tomlin), but Xs and Os and adjustments have NEVER been among them. His shortcomings to adjust during a game are no different than his shortcomings to adjust player personnel or coaches. That is amplified by the current ownership not having the desire or willingness to jump in.
As a players' coach, Tomlin would be best suited to have reasonably capable offensive and defensive coordinators while focusing on his "player-centric strengths." And I would guess the ownership would do whatever he wants relative to the assistant coaches. However, he simply won't do anything with the O coordinator (not sure if he doesn't care, doesn't want to be upstaged, lacks the offensive knowledge to understand or just doesn't have the cajones). On the defensive side, for some reason he feels the need to hide his involvement on D (really odd and, perhaps, causes miscommunication). I mean, he is the head coach, if he wants to run the D he should just come out and say it).
So like, hate or ambivalent to Tomlin, real adjustments are not likely. One interesting note is that, for the first time, the "players' coach" is starting to get pressure from the players. That may ... may ... be a potential trigger for him to finally do things differently. Maybe. But I am not betting on it.
In any case, Canada gives dumpster fires a bad name.
