The hysteria of NFL free agency is long over, but veritable talent remains on the open market.

And for Denver Broncos head honcho John Elway, who's always turning over proverbial rocks, this is the perfect time to swoop in and nab a key contributor. After all, it's a franchise-defining season for Elway's bunch, a collection of new moving parts and holdover star power.

To help break a two-year playoff-less spell, here are a handful of still-free agents the Broncos may be inclined to kick the tires on.

Defensive end Johnathan Hankins: Whether due to financial demands or an undisclosed issue, it's somewhat stunning that Hankins hasn't landed a deal despite youth (26), production (12 sacks since 2014), and a red-hot market when he initially entered free agency. Signing him to a prove-it pact would bolster Denver's defensive line -- Derek Wolfe is perpetually injured and Adam Gotsis faces potential prison time -- while allowing Hankins to rehab his value on a playoff-caliber unit.

Tight end Brent Celek: Now 33, Celek's well past his prime and likely entering the twilight of his career. But the former longtime Eagle is a solid blocker and capable pass-catcher, the former quality being of more interest to a Broncos squad that lost Virgil Green this offseason. He'd also provide terrific mentorship for young tight ends Jake Butt and rookie Troy Fumagalli. Because, let's be honest, Jeff Heuerman isn't cutting it there.

Right guard J.R. Sweezy: Sweezy was a massive bust with the Tampa Bay Buccaneers but proved in Seattle that he can excel in a power-blocking scheme, which the Broncos like to incorporate. The 29-year-old battled injuries over the past few seasons, however, so he'll require medical clearance. If all checks out, Sweezy could be a nice competitor for/backup to presumed right guard Connor McGovern, the weakest link on a revamped offensive line.

Cornerback Kayvon Webster: A key special-teamer on Denver's 2015 championship squad, Webster is coming off a one-and-done stint with the Los Angeles Rams, where he played under former Broncos coordinator Wade Phillips. Webster has hinted at a return to the Mile High City, but nothing materialized. The Broncos appear content to develop rookie Isaac Yiadom and sophomore Brendan Langley behind Chris Harris Jr., Bradley Roby and Tramaine Brock.

Nose tackle Tyrunn Walker: The Broncos did a great job in 2017 identifying and signing Domata Peko, who helped shape the league's fifth-best run defense. He's under contract for 2018 and should continue his high level of play. That's the positive. The negative? There's nobody reputable behind him. Nobody, save for Peko's cousin Kyle, to groom. Nobody to eventually succeed the 34-year-old (in November). Although not starting material, Walker would give Joe Woods a pet project while providing veteran depth on the nose.
