It’s officially the Dak Prescott show in Dallas, at least for now.

The end has now come for both quarterback Tony Romo and wide receiver Dez Bryant in consecutive offseasons, the Cowboys choosing to walk away from a total of seven pro bowls between the two as they officially hand the keys to Prescott going forward. The 2016 Rookie of the Year saw himself stumble on many occasions during his sophomore campaign, a downturn that was attributable to a list of missteps by the Prescott himself and the team as a whole.

Without All-Pro running back Ezekiel Elliott in tow for six games, adding to the absence of All-Pro left tackle Tyron Smith due to injury, the team failed to make the proper adjustments time and again to help put Prescott in a position to succeed.

And for the seemingly few times they did, he struggled with inconsistent accuracy and highly-questionable decision-making as he unsuccessfully tried to will the team into the playoffs. The release of Bryant serves as a spotlight to reveal all of the team’s offensive malfunctions in 2017, and although he accepted his share of accountability for drops and lack of focus while promising better things to come, it was futile when placed against the Cowboys’ want of moving wholeheartedly towards what they’ve labeled as a “Dak-friendly” offense.

Bryant and Prescott never found the chemistry the former had with Romo, and arguably may never have, had they let him stay put.

With both the franchise leader in every passing category that matters and the all-time leader in receiving touchdowns out of the Metroplex, the onus is on Prescott to show up and show out in 2018. He’ll be helped exponentially by Elliott remaining on the field for the entire 16 games (or more), but the fact is the Cowboys can’t run on every single snap. Opposing NFL teams are now calling out the offense’s plays during the game, and that’s far from ideal. Offensive coordinator Scott Linehan, who obviously took exception to Bryant’s criticism of the scheme, is on the hot seat this coming season alongside head coach Jason Garrett — with both of their wagons hitched now firmly to Prescott.

He’s running Garrett’s playbook but it’s one that is far deeper than simply four plays and five personnel sets run in predictable succession, so it’s time he stopped driving the Ferrari like it’s a Ford Festiva. The full-on commitment to convert the offense to than of an RPO (Run Pass Option) will work wonders for Prescott after the team failed to adapt the scheme for him once he took the reins in 2016.

Yes, they’ve admitted now he was still operating within a bubble designed for Romo, but that popped in a big way last season and everyone got wet. A redesign is already underway and Bryant is this year’s sacrificial lamb, setting the stage for a top pick at the position to team up with the newly-signed Allen Hurns.

It'll need to be someone who comes equipped with a jetpack, considering one variable of a successful RPO offense is having a wideout who can blow the top off of the back end of any defense. As it stands, the signing of Deonte Thompson and K.D. Cannon provide hope, but both are operating under one-year deals that will see them enter training camp on the bubble -- so no matter how you slice it, the team needs more there. Having now studied more film of Prescott's days at Mississippi State to give them ideas for how to further tweak the offense, expect things to look drastically different when the Cowboys take the field in September (and not just personnel-wise).

With drastic changes designed to help Prescott solidify himself as the future of the franchise at the QB position, the 2018 season will reveal if the Cowboys made the right move pushing all of their chips onto the No. 4 while the Roulette wheel spins. Contract negotiations on what could be a groundbreaking extension will begin as early as next offseason if warranted, considering the former fourth-round pick has no fifth-year option on his current deal.

If he doesn't deliver in a big way, and after Linehan and Garrett bet their employment on him, it could lead to the dismissal of the latter two while the former finds himself competing head-to-head with backup Cooper Rush in 2019 -- who will be entering the third year of his rookie deal. The Cowboys are hoping, at the moment, Rush will eventually become a trade piece while Prescott ascends to new heights, but should he again stumble they'll have to pump the brakes on that plan.

Letting Rush leave while still having questions about Prescott in what will be his contract year would put the Cowboys in position to forcibly use a 2019 draft pick on another QB, pushing them dangerously close to what they experienced in their post-Troy Aikman days when there was a carousel of inadequate QB's until Romo became starter in 2006.

They will do any and everything possible to avoid that Black Mirror, but what they can't afford to do is look away from it. Doing so will guarantee history repeats itself.
