I did mention, that more money can get added but not greatly, but the kicker to sweeten the deal is the 30M up front. that's very attractive to any player.
According to Spotrac Dak will receive 31 million this season, if nothing changes. His total guaranteed money will also be fulfilled as part of that 31 million.
Why would Dak choose to forgo the opportunity to "get another piece of the pie" by taking the 31 million in one lump some now rather than taking it in 17 weekly installments?
31 million now in exchange for adding years to his contract to help the cap...
OR
31 million paid out over the next four months and the opportunity to negotiate another contract with another big signing bonus and another guaranteed amount.
You really think Dak is going to forgo the opportunity for another big payday simply to get that 31 million now instead of 4 months from now?
The Cowboys are going to have to either eat the big cap hit, (never going to happen) or extend (not restructure) which isn't going to be cheap, and will simply push the big hit down the road.
I understand that what you are suggesting is possible, and has been done in different situations but Dak would be a fool to accept that in this situation. Unless he is motivated more by the chance for a ring than the bag. That seems unlikely since he played hardball for the shorter 4 year contract simply to be in this position, to get another piece of the pie.
