We are not used to this. The Dallas Cowboys are 4-1 and already starting to pull away from the rest of the NFC East. They have an offensive mastermind in Kellen Moore and a badly needed upgrade at defensive coordinator in Dan Quinn. Even Mike McCarthy is getting some grudging respect for the job he is doing. But if you were to really think about who is the most important member of the entire staff, you need to consider that behind the scenes genius, director of scouting and all around personnel guru, Will McClay. Because this year’s edition of the Cowboys may be the most talented roster, top to bottom, that we have seen since at least the height of the Jimmy Johnson glory years.
