Now that former Baltimore Ravens offensive coordinator Gary Kubiak has agreed to become the head coach of the Denver Broncos, per Denver's official site, CBS Sports' Jason La Canfora believes Marrone could be an option to fill that vacancy:

On Sunday, Jan. 18, La Canfora reported Marrone is drawing consideration from multiple teams in the AFC South:

Marrone's stock has seemingly cooled after his decision to leave the Buffalo Bills. While there was some initial buzz that he might land a head coaching position elsewhere, most of those spots have been filled and he has now been linked more consistently with assistant positions.

Marrone Opts Out of Contract

Wednesday, Dec. 31

After two years in Buffalo, head coach Doug Marrone has opted out of his contract with the Bills.

Adam Schefter and Chris Mortensen of ESPN first reported the news and the financial implications:

On Jan. 4, several days after Marrone decided not to remain with the Bills, Schefter reported tension had been brewing within the organization since the 2014 draft:

Seeds of discontent were sown in Buffalo last May, when the Bills traded up to land wide receiver Sammy Watkins. According to sources in the Bills' draft room, former Buffalo head coach Doug Marrone clearly was not happy with the trade. Marrone was not in favor of Buffalo surrendering a future first-round pick to the Cleveland Browns in a trade that did not involve a quarterback, sources said. There are different accounts of exactly how unhappy Marrone was, with some sources recalling he stormed out of the room, and other sources simply saying he walked out of the room.

Tim Graham of The Buffalo News reported on the circumstances of Marrone's exit, while Ian Rapoport of NFL.com reported on Marrone's future and a potential candidate in Buffalo:

Rapoport added another detail on Marrone's train of thought:

The Bills confirmed Marrone's exit in a statement, via Mike Rodak of ESPN:

Bills player Aaron Williams weighed in on the announcement via his Twitter account:

Albert Breer of NFL.com reported on how the coach told Bills players of his decision:

Marrone had little time to turn things around and was saddled with an apparent misfire at quarterback, as the Bills used their maiden first-round pick of the Marrone era on EJ Manuel (No. 16 overall).

Even though the Bills managed a non-losing 2014 season (9-7) with the likes of Manuel and mostly Kyle Orton under center, the need for immediate results seems as prominent as ever in Buffalo. The Bills haven't qualified for the playoffs since 1999.

Prior to Marrone's decision to leave, NFL.com's Chris Trapasso weighed in on the circumstances surrounding the potential of the head coach being fired:

As murky as the offensive side of the ball looks due to the QB depth chart, the defense was among the NFL's best this year, which is some consolation for the turnover this move will create. But it's important the defense remains a strength moving forward.

The Bills have brought in some young offensive weapons in receivers Sammy Watkins and Robert Woods. It's key to find someone superior to distribute the ball to them, and to also upgrade the running game and offensive line, notably the guard positions. Holding on to free-agent-to-be C.J. Spiller if possible would be a plus for the Bills.

As for Marrone, he likely did enough with his first stint as an NFL head coach to receive some offers from other teams, if not as a head coach then as an offensive assistant. It's also possible that he decides to return to the college ranks, where he previously helped turn around the Syracuse program.
