In Denver, poor quarterback play doomed the Broncos last season as the team stumbled to a 5-11 record, its worst campaign since 2010.
Keenum worked with former Broncos head coach Gary Kubiak, now a senior personnel advisor in Denver's front office, with the Houston Texans from 2012-13 having joined as an undrafted free agent.
Speaking of Keenum, the tweet also mentions that he could be a fit in Buffalo, which simply means that every National Football League franchise without a quarterback - hello, Bills - will be linked, rumored, and whispered to be interested in the bevy of signal-callers likely to be available from Minnesota.
Only the winless Cleveland Browns threw more interceptions than the Broncos' 22, and Denver had just one receiver catch more than 50 passes and finish with more than 560 yards receiving - Demaryius Thomas with 83 catches and 949 yards.
Keenum went 11-3 with 3,547 yards passing, 22 touchdowns and seven interceptions and threw that last-second heave to Stephon Diggs to stun the New Orleans Saints 29-24 in the playoffs. They also can go the best-player-available route with the No. 5 pick of the draft and could end up with one of the two best players on the board - Saquon Barkley or Bradley Chubb - if the run on quarterbacks comes at the top of the first round.
The Broncos haven't made the playoffs since their Super Bowl win to close out the 2015 season.
Elway said in recent weeks he still believed the team could get back into the postseason mix with an upgrade behind center. We just have to figure out a way to get it right.
Siemian, Lynch and Chad Kelly, a seventh-rounder past year who sat out his rookie season with injuries, remain on the roster. We didn't play well there past year.
