The Denver Broncos boast a quarterback depth chart that consists of future Hall of Famer Peyton Manning and little else of significant value.

Brock Osweiler, the team's former second-round draft pick in 2012, is still on the roster, but his chances of playing anything even resembling meaningful snaps next season falls squarely on the spectrum somewhere between slim and none.

According to the latest report, the Broncos and GM John Elway may be eyeing a local draft prospect - Colorado State University QB Garrett Grayson - as the team's potential future at the position, while Osweiler may not be long for the Denver roster.

"The team that seems to be highest on Grayson is the hometown Denver Broncos," reports Tony Pauline of Draft Insider. "The feeling is Grayson is the most capable of running the system that Gary Kubiak will employ in Denver; a system similar to the one Grayson ran at Colorado State. He also has the arm strength necessary to get the ball through the cutting winds that often blow through the Mile High City. There's also a strong belief Brock Osweiler, who's in the final year of his rookie contract, won't be with Denver after this season."

Grayson participated in the CSU Pro Day Monday, running a 40-yard dash in the 4.5 and 4.6 range and, more importantly, tossing 74 passes and missing on just three, according to Pauline.

Grayson, who didn't throw at the NFL rookie scouting combine due to a hamstring injury, told ESPN that he felt he'd done enough at his Pro Day to cement his status as the third best quarterback in the draft behind Jameis Winston and Marcus Mariota but that he's striving to be No. 1.

"I proved what I can do today," Grayson said. "I think I'm up there with the best, I think obviously everyone knows Winston, Mariota are kind of the 1-2. But as quarterbacks, or any position, you should always be pushing, always fighting for the No. 1 spot at your position, no matter who's out there."

Grayson threw for 4,006 yards, 32 touchdowns and just seven interceptions last season for the Rams.

Osweiler has never completed more than 11 passes in any of his three NFL seasons. The 6-foot-8, 240-pound signal-caller has a career 82.5 passer rating and has one touchdown and zero interceptions as an NFL player.
