This is one of those few situations where everyone wins.
Adrain Peterson wins. He gets to play for his childhood team. He gets to play behind this O Line. He plays for a team many will feel is a Super Bowl contender.
Demarco Murray wins. He is going to get a very big contract. Sure, he wanted to stay in Dallas, but the contract he is about to sign will ensure his grandchildren never have to worry about money.
The Minnesota Vikings win. They move on from a bad PR situation and free up a ton of cap room. Coach Zimmer can go out and sign 3 or 4 starters with the cap room created by Peterson's departure.
The Dallas Cowboys win. You lose Murray and you get All Day...are you kidding me? Plus, he's going to play like a man possessed after sitting out last year.
Jerry Jones wins. Adrian Peterson signs on Monday. Several thousands of #28 Cowboy jerseys sold by Tuesday. Cha Ching!
The NFL wins. A year removed from an ugly year with domestic violence issues, the NFL will also benefit from the buzz and media attention from Peterson joining America's Team.
