The Great Denver Broncos quarterback competition doesn’t start until we say it does.

A big part of the job: Representing the team – and the city – in press conferences.

And so the QB competition began Thursday when both Paxton Lynch and Trevor Siemian met the media.

The confidence Lynch exuded was impressive.

“Obviously, I believe in myself to be the starter this year,’’ Lynch said. “I’m going to work hard just like I did last year. I’m going to learn the offense, get extra work with these guys when I can and be in the building as much as I can at this time. That’s what I’m aiming for. That’s what I want to do.”

Sounds like a new guy.

Siemian, meanwhile, stood up there like he’s been there before. He was the starter last year and yet new coach Vance Joseph said its wide open competition. Siemian has too much equanimity to be offended.

“With all due respect to Paxton, you’ve got to be on edge wherever you are,’’ Siemian said. “You’ve got to earn it every day. Not just quarterbacks, but all across the board. You don’t really need any extra motivation, regardless of circumstance or whatever you’re talking about. You’ve got to earn your stripes every day. Moving forward, that’s what I’ve got to do if I want to play for a while.”

Sounds like the same guy.

So which quarterback took the early lead? It doesn’t matter. Mark Sanchez was the guy at this time last year. He wound up among the team’s final cuts.

What will matter are the preseason games. So says the media.
