You can't just create a game plan and then that's what we are sticking with come hell or high scores. The best offenses, and no I'm not including the Texans in that, switch it up not even have half time but play to play to learn what works. Brady is not a great example because he's Brady but its all I have time to think of right now. If a defense shuts down Brady's short pass he goes to the long bomb, if they shut down that he goes to the short pass, if they manage to shut down the pass altogether that start running it. That's the kind of stuff you have to deal with.
People compare it to chess but I don't like that comparison because in chess but sides are equal and both players have a plan they tend to stick to. I compare it more to poker, you may have better cards than the other guy but if he plays his hand better and makes you scare to bet then he is going to win no matter what the cards are. RAC looked scared to bet in that game and NO upped the bet till he folded. Didn't help that Brees is always an ace you know they are holding.
