Broncos' updated offensive line depth chart with Kage Casey

The Denver Broncos added one offensive lineman during the 2026 NFL draft last week — Boise State's Kage Casey in the fourth round. After that, Denver brought in Iowa State offensive tackle Tyler Miller and Weber State lineman Gavin Ortega as undrafted free agents .

All five of the Broncos ' starting offensive linemen are returning this season, so the incoming rookies will be competing for backup roles this summer.

Miller played as a right tackle in college, and he's probably a swing tackle prospect in the NFL. Ortega was also a tackle in college, but he could be a candidate to move inside to guard or center as a pro. Casey is also a versatile prospect. Casey was a left tackle with college football's Broncos, but it wouldn't be surprising to see him used as a swing tackle/guard in Year 1.

Here's a look at the projected offensive line depth chart going into the summer.

Broncos offensive line depth chart

• LT: Garett Bolles , Frank Crum

• LG: Ben Powers , Kage Casey, Nick Gargiulo

• C: Luke Wattenberg , Alex Forsyth , Michael Deiter

• RG: Quinn Meinerz , Calvin Throckmorton , Matt Peart

• RT: Mike McGlinchey , Alex Palczewski

• Depth: Marques Cox, Tyler Miller, Gavin Ortega, Nash Jones

(Note that this is a projection , not an official depth chart from the team.)

Several players will be backups at multiple positions, such as Palczewski and Casey providing cover at both tackle and guard. Throckmorton and Peart will be key veteran swing backups to watch this summer as younger linemen push for their spots.

Broncos veterans report for the start of the offseason program on Monday, and rookie minicamp begins later in the week ( May 8-10 ).
