Who cares if they ‘cheated’? Then adjust at halftime. The Rams were AHEAD. Falcons shredded Pat’s in 1st half by bringing all new plays. Belichick made huge adjustment at halftime and prevailed. Man up Dickerson.
The rumored ( no actual witness of them doing so, or of film, and the article alleging it was retracted because there was no actual source) filming was of red zone offense walkthroughs - which the Rams were 2-0 in.
Just a team getting outsmarted and viewing it as magic.
