The Denver Broncos laid the failure in 2017 at the feet of the quarterback.

After watching Trevor Siemian, Brock Osweiler and Paxton Lynch flounder all season, GM John Elway stated the obvious on Tuesday: Denver's "No. 1 goal" is to upgrade the QB spot this offseason.

"I think there is no doubt we've got to get better at that position," Elway said, via the team's official website. "For us to have a chance to get better, we've got to get better at that position."

Broncos quarterbacks finished 2017 with a 73.0 passer rating for the season, 31st in the NFL -- only the Cleveland Browns signal-callers were worse. Denver's trio of QBs also ranked 31st in INTs (22), 27th in completion percentage (58.7), 27th in yards per attempt (6.5) and T-25th in passing TDs.

"Obviously, that position didn't perform as well as we wanted it to. I thought it would perform better than it did," Elway said. "And it's not just on them; I think there's a lot of circumstances that went into that, that put them in tough situations. But we didn't perform as well as we'd like to, so that's obviously a position that we feel like we have to get better at going into next season."

Behind a porous offensive line, Siemian cratered, tossing a bevy of terrible interceptions before ending the season injured. Osweiler is Osweiler.

One problem for Elway heading into the offseason is the little in-game evaluation the team received on former first-round pick Paxton Lynch. The second-year pro started just two games and was injured in his first start of the season. In the 2017 finale, Lynch led a quick-pass offense and showed that he has the arm to be a starting QB. The raw signal-caller, however, repeatedly threw late, displaying a tendency to be slow reading his progressions.

Elway must decide if Lynch's struggles are simply part of the process of a growing quarterback with limited snaps or a sign the team needs to move on.
