One of our patterns has been that we let the other team march down the field on its first drive, presumably so we can "see what their gameplan is," lull them into a false sense of "hey, it's working" security, and then we adjust while they continue to beat the same drum.
I have to believe that other teams see that pattern and the easy counter is to do one thing on the first drive and then switch it up the next time you get the ball, and keep switching it up, staying one step ahead.
I'm not good enough at X's and O's to know whether the Pats and Falcons (and maybe to some extent the Saints) did that. But my sport is baseball and that's what good pitchers do, switch it up the second and third times through the lineup.
Anyone have any thoughts?
