They’re called half time adjustments, you see what your team is doing well and not, you see what the other team is doing well and not, and you tweak your plan accordingly. Belichick has a long history of being the half time adjustment master, he’s also the rematch master. He learns.
I am talking about the amazingly horrible fumble call that set the Patriots up for a go ahead touchdown. There was also pass interference called on the Dolphins when the defender never even touch the receiver.
It isn’t half-time adjustments. The NFL is rigged in favor of their markee teams.
