Cowboys vs. Jaguars: 4 questions that remain unanswered

The Dallas Cowboys are entering Sunday with the Jacksonville Jaguars in their sights. The game will mark the Cowboys’ fourth and final preseason contest of the year, and figures to be a point of no return for some players on the currently bloated 80-man roster.

Final cuts are looming with the all NFL team required by the league to trim their roster down to just 53-players by this Tuesday. Expect a flood of transactions between now and then as teams look to the waiver wire and free agency to upgrade their roster.

Still, entering the final preseason game, the Cowboys have some lingering questions that need to be answered before their Week One matchup against the Tampa ay Buccaneers kicks off in less than two weeks. Here are the four biggest questions left in our minds …

Who’s the backup quarterback in Dallas?

Garrett Gilbert or Cooper Rush? That’s really the question that still needs to be answered. Which one will be the primary backup to starting quarterback Dak Prescott prior to final cuts? Second-year passer Ben DiNucci has all but eliminated himself from that conversation after his three-interception performance against the Houston Texans last weekend.

While Gilbert has started every game in the preseason so far, his performances have been mediocre. And Rush is coming off a stellar game against Houston where he completed 10 of his 12 passes for 97 yards and two touchdowns, by far outperforming both Gilbert and DiNucci.

Rush earned himself reps with the first team in practice this week and was named the starter against the Jaguars on Sunday. Another solid performance could earn him the primary backup role, a spot he occupied during his three first NFL seasons in Dallas.

But even if Rush is able to impress against the Jags, it might all be for not if the Cowboys find a more experienced passer available on the waiver wire or free agency during final cuts in the coming days.
