Should the Cowboys sign Darrelle Revis?

Dez Bryant made some noise on Twitter on Saturday evening, and brought up an interesting question.

Should the Dallas Cowboys go after Darrelle Revis?

Bryant made his personal answer clear as he attempted to recruit Revis with his tweet, but unfortunately for the receiver, he doesn't get to make roster decisions.

It wouldn't be a slam-dunk signing for the Cowboys, as Revis' skills have declined and he'll likely require a salary of at least $6 million. However, that doesn't rule out the possibility of Revis Island relocating to Dallas.

Let's take a look at both sides.

The case for signing Revis

Revis would become the sixth-highest paid Cowboys player in 2017 if the team meets his $6-million tag, but with $16.8 million in cap space, Dallas could afford the salary and still have some breathing room to work with.

Revis wouldn't need to take on opponents' top receivers anymore, but could teach younger Dallas defenders how to do what he once did. The Cowboys spent a second- and third-round pick on corners Chidobe Awuzie and Jourdan Lewis, respectively, while Anthony Brown, a 2016 sixth-rounder, is also early in his career and is expected to start as a sophomore.

The Cowboys do have seasoned cornerbacks Orlando Scandrick and Nolan Carroll on the roster, though they may be looking to get rid of the latter. The 30-year-old Carroll was arrested for DWI in late May just months after signing a three-year, $10-million deal - not exactly what the team is looking for from its veteran leadership group.

There's also the PR angle. Few cornerbacks have commanded the reputation and enjoyed the star power that Revis has, which could make him an ideal fit for Cowboys owner Jerry Jones, who loves making headlines with personnel moves. While Revis may not earn all his money on the field, his merchandise sales and impact on Dallas' young secondary might make him worth a deal.

The case against signing Revis

As mentioned, Revis is not the player he once was - regardless of what Bryant may think. If he were to sign for $6 million, he would be paid as the Cowboys' top cornerback, but wouldn't play that role on the field.

Assuming they don't cut Carroll (since they would have to pay him $3 million to not play) or any of their draft picks, the Cowboys will already have six corners - Scandrick, Carroll, Brown, Awuzie, Lewis, and sixth-rounder Marquez White - without Revis. Few teams carry more than that number on their 53-man roster, especially when three of them are at least 30 years old.

Revis is clearly no longer a lockdown cornerback, and his best role at this point is up for debate. His experience as an outside man-to-man defender likely won't translate well to becoming a nickelback, while keeping him as a regular player on the outside is just asking for quarterbacks to test his declining skills. A move to safety could be in the works, although the Cowboys have already found their stud deep coverman in Byron Jones, and Revis' skill set likely won't make for a smooth positional switch.

Even without an injury, Revis may end up barely playing, which could kill his confidence and embarrass the front office that made him their highest-paid defensive back.
