There were 100% halftime adjustments. Just not the kind that everyone talks of when they say it where we completely switch philosophy in a short timeframe.I knew this is what people would say, but I think it's only half correct. You and @Simba have said the same thing. The offense has been more multiple so pivoting is easier. That's facts.
But it clearly wasn't on the fly. If it was then the adjustments would've come earlier. Look no further than the most stark differences literally being the last drive before half (maybe the worst drive of the season that didn't end in a turnover) and the first after the half.
Could have been something as simple as…
Monken: Lamar, what are you seeing?
Lamar: They’re blitzing heavy
Monken: Want to get more short game a quick reads?
Lamar: Yes
Not like these guys scrapped a playbook on a whim, but it certainly gave a chance for a quick discussion and an opportunity to pivot into stuff we’d done previously.
