Two years ago, the Denver Broncos won Super Bowl 50 despite having a less-than-stellar Peyton Manning leading the charge from the quarterback position.

Granted, a broken-down Manning is still better than the other options the team had at the time, as the transition to Paxton Lynch and Trevor Siemian didn't go according to plan last year.

However, with both players now having NFL experience, they were expected to come into training camp looking good and looking ready to lead the Broncos offense.

Through the first weekend of training camp, though, first-year head coach Vance Joseph has been less than impressed with the two quarterbacks, telling NFL.com that both Lynch and Siemian need to get better in a hurry:

"Did I like what I saw? Not really. Both guys had issues today," Joseph said of his offense "I didn't like what I saw today. Honest. They both struggled today."

Obviously, it's still early in camp, and the Broncos have an incredible defense, but the fact that Lynch and Siemian have both been disappointments doesn't bode well for the upcoming season.

Joseph added that the entire offense struggled over the weekend, but when your quarterbacks aren't playing well, it's tough to get anything going on that side of the ball:

"It was a rough day for the offense today," Joseph said. "The defense came out with great intensity and made some big plays in the red zone, which is huge. On game days that's a 10-point swing. We don't want that for our offense, but defensively it was a good day."

With Von Miller rushing the passers, a stacked secondary and a talented linebacking corps, the Broncos' defense is a nightmare for any quarterback - not just Siemian and Lynch.

However, the second-year Lynch and third-year Siemian are running out of time to stand out in the competition to earn the team's starting job:

"We've got two good young quarterbacks. We can win with both guys," Joseph told Davis on NFL Network. "Who is the best for us? I'm not sure yet. That's why time is so important. Now, time is coming to an end, the next three or four weeks here. So, both guys are putting in work. Both guys want the job. I'm not sure who is best for us right now. Whoever is best for us that is who we are going to play."

The Broncos finished a decent 9-7 last year, thanks in large part to the defense. If they don't take a step forward offensively this year, though, they'll likely miss out on the playoffs once again, as the AFC West will be tough.
