Kirk Cousins, who spent his first six National Football League seasons with the Washington Redskins, is the top free-agent quarterback available (not counting Drew Brees, who is expected to remain in New Orleans).
The terms of the agreement are unknown.
Case Keenum's brief tenure with the Vikings appears to be over.
Elway is now in his eighth year as the Broncos' chief decision-maker.
For Keenum, he will now face a pile of expectations in a quarterback-crazed region that saw its team win a Super Bowl just two seasons ago.
Miller was in Elway's first draft class - in 2011. Joseph is now Denver's head coach.
The Denver Broncos have apparently worked out their quarterback situation ahead of the official start of free agency.
In order to try to recapture a little of that history, the Broncos went after Keenum and got him. The Browns, meanwhile, have several options at quarterback while the Jacksonville Jaguars could seek an upgrade over Blake Bortles. Here's the fourth of a series assessing the Vikings' top five needs and how they could address them in free agency.
The former number one overall NFL Draft pick has been with the Rams, Eagles and Vikings, and could be headed to yet another new city this offseason depending on what happens with the Vikings' pursuit of Kirk Cousins.
The Broncos had three quarterbacks start games this past season - Trevor Siemian, Paxton Lynch and Brock Osweiler - but it was a bumpy ride on offense as the Broncos were among the league leaders in turnovers and offensive coordinator Mike McCoy was sacked in November.
In short, the Broncos have to be right on this one. He has just two playoff starts in his career - both this past January - or two more than Trevor Siemian or Paxton Lynch.
Now the Broncos hope he can replicate that play for the forseeable future in Denver. Having a quarterback that can help us become a more efficient offense and help us score more points and not turn the ball over, that can only help us get better.
