The Broncos released their first depth chart of 2015 on Monday, four days before their preseason opener at Seattle on Friday.
Some surprises were included, but coach Gary Kubiak urges caution.
"Don't read too much into what's going on up front or anywhere," he warned Sunday. "It's going to be very competitive. They're going to win and lose jobs in these preseason games and going against good players."
The young and inexperienced offensive line got younger and even less experienced in the second week in camp as Kubiak bumped up rookie guard Max Garcia and second-year center Matt Paradis to the first team.
