Kellen Moore and Andy Dalton have a history. In 2010, Moore and the Boise State Broncos defeated Andy Dalton and the TCU Horned Frogs 17-10 to complete a 14-0 season in the Tostitos Fiesta Bowl.
So while Dak Prescott is holding out, Andy Dalton and Kellen Moore can compare notes and develop strategies for the offense- with Mike McCarthy overseeing. This puts a very established veteran in the driver's seat if a quarterback competition even begins to take shape.
I doubt if Dalton respects anyone in the Cowboys organization more than Kellen Moore. And vice-versa.
If the need arises, Dalton very well could earn that extra money in his contract.
I would not be surprised to see Dalton under center in week one, and if that happens, see the most potent Cowboys offense in over a decade.
