Without a doubt, the biggest storyline in Dallas this offseason is the status of quarterback Dak Prescott.

The Cowboys have extended the exclusive franchise tag to Prescott, meaning they hold his rights exclusively and no other franchise can even discuss a contract with the quarterback. Prescott is coming off his rookie NFL contract, with has proven to be one of the most team-friendly contracts in the NFL in recent seasons.

The quarterback made just over $2 million last season after earning $630,000 in 2018, $540,000 in 2017 and $450,000 during his rookie season in 2016.

If he plays for the franchise tag, Prescott will make over $30 million next season but his contract will be only a one-year deal — as are all franchise tags.

During a recent appearance on 105.3 FM The Fan’s “K & C Masterpiece,’‘ NFL analyst Chris Simms offered up the huge contract the Cowboys have offered Prescott, according to his sources, to keep the quarterback in Dallas for years to come.

“From what I know of the situation, alright, and I know from some people who are in the know, he’s been offered five years, $175 million,” Simms said on the show. “He wants a four-year deal. If they do agree to a five-year deal, they would like a really big number at the end of that fifth year to cover their butts for what the market might be at the position five years from now. And I’ve heard he’s asking for somewhere like north of $45 million in that fifth year.”

So much for Prescott having a team-friendly deal.

That was inevitably going to change once his rookie deal ran out but it remains to be seen how high the Cowboys are willing to go to lockdown Prescott. Apparently, making his the league’s highest-paid player may not be enough to get that done.
