The Dallas Cowboys getting a deal done with Dak Prescott even before the franchise tag deadline was a move that opens up possibilities for the offseason. The team has their starting quarterback locked up now, and he is getting the money he richly (pun intended) deserves. And also very importantly, his cap hit has been greatly reduced from what it would have been under the franchise tag, making the impending free agency period much more manageable.
Of course, the downside of that is that those cap costs have now been pushed into the latter years of the contract.
