INDIANAPOLIS — The Broncos made it clear at the 2020 NFL Combine that Drew Lock is an overwhelming favorite to line up under center for the Broncos' season opener.
Who that center — and the players around him — will be? That's far less clear.
Connor McGovern, who started all 16 games at center for the Broncos in 2019, is an impending free agent. And while John Elway said Wednesday that the Broncos would discuss a potential new contract with McGovern, Denver could be in need of a new center in just over three weeks.
The Broncos also have a hole to fill to McGovern's right, as Elway said the Broncos will decline the team option on Ron Leary's contract.
Denver also must decide in the coming weeks whether to exercise the fifth-year option on 2017 first-round pick Garett Bolles' contract.
In short, Offensive Line Coach Mike Munchak's unit is in flux — and the resolution may not be clear until after the 2020 NFL Draft.
"It was OK," said Head Coach Vic Fangio of the offensive line play in 2019. "You know those new commercials? 'It's just OK.' Well, that ain't good enough. That's about what it was."
Fangio said injuries to Leary and Ja'Wuan James helped the Broncos develop young players late in the year, and that could provide some direction for Denver as it tries to reshape the line.
"[Elijah] Wilkinson plays basically the entire season," Fangio said. "We got Pat Morris in there, we got [Austin] Schlottmann in there, and we fill good about those guys now. Those three guys are added to the mix. We think some of them have starter capability or really good backup capability."
If the Broncos choose to add exterior pieces to the line, they could look to free agency — Washington guard Brandon Scherff could be available — or the draft.
The following players are NFL Network's highest rated players at each position and could be options for the Broncos if they choose to use an early-round pick on an offensive lineman in April:
G Tristan Wirfs, Iowa
The 2019 second-team All-American played all 13 games at tackle last season, but NFL Network's Daniel Jeremiah thinks he could be better served to move to guard for a team.
"Overall, I believe he can survive at tackle, but he'd benefit from playing with neighbors on both sides," Jeremiah wrote for NFL.com. "I think Wirfs has All-Pro potential at guard."
Wirfs is Jeremiah's 13th-ranked prospect, and he said he met with the Broncos in Indianapolis.
"I think I'm pretty powerful," Wirfs said of his best attribute. "I think I can move guys off the line of scrimmage."
C Cesar Ruiz, Michigan
Ruiz, a junior from Michigan, drew a comparison to Dallas' Travis Frederick from Jeremiah. The potential first-round pick was a two-time All-Big Ten player and was rated the best pass-blocking center in 2019 by Pro Football Focus.
"If you look at the film, if you look at how I dominate people, if you look at my character, how smart I am, I have everything for a first-rounder," Ruiz said Wednesday. "I'm very confident in myself that I am a first-rounder."
Ruiz said he also had a formal visit with the Broncos, and he's willing to move to another position, if needed.
"I'm a versatile player," Ruiz said. "I could play guard, center, whatever you want me to play on the interior, I'm comfortable playing anything."
T Mekhi Becton, Louisville
Becton, Jeremiah's fifth-ranked prospect, could be long gone before the Broncos are scheduled to pick at No. 15.
If a run on quarterbacks begins, though, Becton could fall down the board. In that case, the Broncos may find themselves able to select one of the draft's premier players.
The 6-foot-7, 368-pound player is "a rare athlete" with upside that is "through the roof," according to Jeremiah.
He's also confident.
"I feel I'm the most dominant tackle in this draft," Becton said. "You wouldn't go wrong picking me.
"… The tape shows it. It shows that I finish almost every play. It's as simple as that."
