Darrelle Revis has cleared one big obstacle in the final wave of NFL free agency, learning that he won't face any league discipline after his felony criminal charges were dismissed.

There's still another major hurdle standing between him and re-employment — the fact he's a fading cornerback who turns 32 in July and isn't built well to extend his career as a safety.

Revis, released from his second Jets stint in March, has seen many lukewarm suitors round out their secondary since. That limits to him one relasitic option: the Dallas Cowboys.

It's one contending team that could use more experienced depth at defensive back. It's also the team that likes taking flyers on veteran big names, regardless of what may have happened off the field.

The Packers went bargain bin early with former Jaguars starter Davon House, then used second-round picks on corner Kevin King and safety Josh Jones. The Cardinals stood pat with Brandon Williams opposite top corner Patrick Peterson, but added Antoine Bethea, Tyvon Branch and Budda Baker at safety to make up for losing Tony Jefferson and D.J. Swearinger.

There won't be a Revis return to his home college town of Pittsburgh, either. The Steelers stayed young behind starters Artie Burns and Ross Cockrell with rookies Cameron Sutton and Keion Adams.

There also won't be a Revis reunion with the Patriots. They kept Malcolm Butler at shutdown and Duron Harmon at nickel with a splurge on Stephon Gilmore to replace Logan Ryan. They are rather deep at both safety and corner.

It's not surprising that Jason McCourty, who was released by the Titans only a week before the draft, didn't need to worry much about finding another team. He is a younger, more versatile defensive back than Revis, and got signed that way by the Browns (at two years, $6 million) last week.

Revis looked terrible covering wide receivers in 2016, and there's no indication that his eroding skills will get a new life at a new position. It will also be hard to shake the "disinterested" dissing he deservedly got.

He doesn't exactly fit Dallas, either, with its zone coverage scheme. The Cowboys, however, despite drafting four defensive backs — Chidobe Awuzie, Jourdan Louis, Xavier Woods and Marquez White — is very green at the position. Second-year man Anthony Brown and 30-year-old Nolan Carroll are the projected starters after the team moved on from both Morris Claiborne and Brandon Carr. There's also a transition at safety, where Jeff Heath is working to replace Barry Church.

Revis doesn't feel like a worthy upgrade, but it's in the nature for the Cowboys to give someone such as Ravis a chance in that mix. He's already getting his $6 million from the Jets, so the questions are, does he and would he want to play for less, and will he go out and prove he deserves to be paid anything?

For the Cowboys, other than the facade, there's limited upside with Revis. But with the destinations dwindled, they are the only semi-logical spot for him to extend his Hall of Fame career.
