Dak Prescott’s brother criticized the Dallas Cowboys after the team failed to reach a long-term agreement with its star quarterback prior to Wednesday’s deadline.

Tad Prescott said on Twitter he had never been a Cowboys fan growing up, adding “who knows how much longer I’ll be cheering for them” after today’s events.

Not only did the Cowboys not extend Prescott, but the two sides reportedly had not spoken about an extension in weeks. Jane Slater of NFL Network said the final over was “between 33-35M annually with 100M guaranteed.”

But there is really no incentive for Prescott to sign that kind of deal. He will make $31.4 million on the tag this year, and can make $37.69 next season.

In other words, Dak will make in excess of $34.5 million in average value for the next two years as he awaits an even richer contract.

The Cowboys had limiting spending capital to begin with, which is why the likes of Byron Jones and Robert Quinn were allowed to walk in free agency. Dallas did re-sign star wide receiver Amari Cooper for five years and $100 million, but that was about the only big-money deal the Cowboys struck as they braced for a potential extension with Prescott.

Instead, the former fourth-round pick will bet on himself.

Dak had a career year in 2019, throwing for 4,902 yards and 30 touchdowns against 11 interceptions while also ranking fourth in terms of total QBR, per ESPN.

Playing on the tag comes with a good deal of risk. But if Prescott continues to ascend, he will have made the Cowboys look foolish.

Dak’s brother certainly believes Dallas should have negotiated in better faith.
