The Cowboys have offered quarterback Dak Prescott one of the largest contracts in NFL history a source said. The Cowboys’ proposal to Prescott is more than what Los Angeles Rams quarterback Jared Goff and Philadelphia’s Carson Wentz received in their extensions last year.

As it stands, the Cowboys placed the exclusive tag on Prescott on Monday to a projected $31.6 million. However, Prescott’s agent, Todd France, and the franchise continue to talk about reaching a long-term deal.

One of the major holdups in the deal is length. Prescott would like a four-year contract while the Cowboys want a five-year deal.

A shorter deal would allow Prescott to come back to the table, after large contracts are settled with Kansas City’s Patrick Mahomes and Houston’s Deshaun Watson. Prescott will be 30 in 2023, the last year of an expected contract, which would be in his prime.

In the last year, Goff, Wentz and Russell Wilson, reached new deals that set the market for that position.

All three quarterbacks, with one year remaining on their deals, received four-year extensions. Wilson signed for a total of $140 million with $107 million guaranteed. Wilson has the highest average salary in the NFL at $35 million.

Wentz also signed a four-year extension worth $128 million with $107.9 million in guarantees. Wentz averages 32 million per season. Goff has the highest total guarantees at $110 million and averages $33.5 million per season.

The last known figures the Cowboys have offered Prescott was an average salary of $33 million with guarantees of $105 million. But now they’ve surpassed those numbers as they seek to end these talks.

The Cowboys have until July 22 to sign Prescott to a long-term deal or he will play the 2020 season under the franchise tag.
