The Cowboys remind me of that "Brawler" that tells everyone he's going to be technical in his next fight. Then fight night comes, and he's dancing around for the first couple of rounds. Next thing you know, his opponent lands a nice one and all that nonsense he was talking all through his camp goes out the window. He bites down on his mouthpiece and starts swinging his arms like windmills.
We aren't good enough to do things we hope work, we have to do what we know works. We talk a lot of crap all offseason, but once the heat is on, you do what you know.
