The Broncos won the Super Bowl with plenty of questions at the quarterback position, and now, five months later, they're trying to figure out who will replace Peyton Manning and Brock Osweiler. The former retired after a Hall of Fame career -- but a forgettable final season -- and the latter bolted for a big pay day with the Texans.

That leaves journeyman Mark Sanchez, unproven second-year player Trevor Siemian and rookie first-rounder Paxton Lynch. Conventional wisdom is that Sanchez could hold things down while Lynch makes the transition from college to the NFL.

Earlier this month, Broncos safety T.J. Ward said the race for the starting job "looks pretty even." His comments came weeks after coach Gary Kubiak said that Sanchez and Siemian were neck and neck. But now, with training camp just around the corner, Broncos defensive tackle Sylvester Williams has weighed in -- though his remarks differ from those previously made by Kubiak.

"Right now, they're giving all three of those guys equal reps, so I don't think either one of them has created any advantage at this point, because they haven't consistently been with the ones yet," Williams told Sirius XM NFL Radio's Tom Pelissero and Bill Polian. "But I think, going into the camp, I think Coach Kub kind of let us know he's going to go with Mark and give Mark the opportunity to see what he can do and then go on from there."

Seems reasonable, especially given how far the Broncos' defense took them last season, all while Manning was one of the NFL's worst quarterbacks, according to Football Outsiders' advanced metrics. (Specifically, Manning ranked 36th ahead of only Nick Foles.)

However the depth chart shakes out in the coming weeks and months, Sanchez, who has had his fair share of battles, is looking forward to the competition.

"Listen, I don't care who is there, what is going on right now," the former Jets and Eagles quarterback said back in April. "They are going to give me a fair shake, that's all I can ask for, a fair shot. I am good. Let's go. I will bet on myself and compete my butt off. I will be friendly and professional with whoever is there. But I want this bad. Really bad. I want what they experienced last year."

And while Sanchez embodies "replacement-level QB," the bigger wild card is whether the Broncos' defense can replicate its 2015 success. Von Miller has a well-earned new deal, but Malik Jackson and Danny Trevathan left in free agency.
