Why would anyone want the Cowboys to move out of the NFC East? The Cowboys have some of the best rivalries in NFL history. Not to mention that playing the east coast teams is part of the reason the Cowboys are as popular as they are. There is no way they would be as popular as they are now if they were playing the Rams, Seattle, and San Fran twice a year instead of New York, Philly, and Washington.
Besides that the NFC East is almost always one of the best divisions in the NFL. I for one want the Cowboys to play the best teams and those teams are definitely not found in the freakin NFC West.
