John Elway will need to get creative this offseason if he cannot re-sign Brock Osweiler.

The long-time backup to Peyton Manning becomes a free agent next month. The club will probably not be able to slap Osweiler with the franchise tag because it reportedly plans to use that designation on star outside linebacker Von Miller. The quarterback's agent will seek a big contract because he plays the most lucrative position in football and showed promise over six starts last season. In other words, it's no given that Osweiler will be in a Broncos uniform in 2016.

Does that make Denver a viable destination for Robert Griffin III? The Broncos are doing their due diligence on the former NFL offensive rookie of the year, according to Denver radio host Benjamin Allbright. There's no indication of serious interest yet, and this is the time of year when front offices evaluate anyone even remotely on their radar. But let's explore the potential here.

Griffin has not played since 2014 — he spent all of last year on the bench. He won only two of seven starts in 2014, throwing four touchdowns and six interceptions. This did not appear to be the same player who set the league on fire and led Washington into the playoffs as a rookie in 2012. It's been a steep fall since he tore up his knee in a postseason loss to the Seahawks more than three years ago.

It could take time for Griffin to adjust to a pro-style system after he starred in Baylor's wide-open spread and with a zone-read scheme in Washington. But the potential may be there for him to rebuild his NFL career. Coach Gary Kubiak, a former backup QB in the league, generally gets the best out of his signal-callers. The presence of Elway, a Hall of Fame quarterback, could only help. Though they might not turn RGIII into a star, it would not be a bad situation for him to fall into. A support system is in place with the Broncos.

Washington will probably either cut or trade Griffin in the near future. The fifth and final year of his rookie contract is not guaranteed, so the club does not owe him anything. Once the 26-year-old hits the open market, he will draw plenty of interest because he was once such a dynamic player and he should come with a relatively low price tag.

The Broncos would only have interest in Griffin if Osweiler slips from their grasp. But it's an intriguing idea, one worth watching this offseason.
