Boise State offensive lineman Kage Casey is considered one of the top prospects in the 2026 NFL Draft, with draft analysts projecting him as a fourth or fifth-round pick who could transition from tackle to guard or center at the next level. Casey was a multi-year starter and All-American at Boise State, but scouts have noted concerns about his lower-body stiffness and ability to handle speed rushers on the edge.

Why it matters

As one of the few Boise State players expected to be drafted, Casey's evaluation by NFL scouts provides insight into the program's ability to develop pro-caliber talent, especially along the offensive line. His potential position change also highlights the importance of versatility for interior offensive linemen in the modern NFL.

The details

Draft analyst Dane Brugler of The Athletic ranked Casey as his No. 10 guard prospect, praising his assignment-sound blocking and ability to work around physical limitations. Fellow analyst Doug Farrar believes Casey's best fit in the NFL is as a guard or center, where his athleticism and hand strength can be better utilized. At the 2026 NFL Combine, Casey measured in at 6-foot-6, 310 pounds with 37 3/4-inch arms and 10 1/4-inch hands, earning an overall prospect grade of 6.25 that ranked 12th among the 56 offensive linemen in attendance.

  • Brugler released his 2026 NFL Draft guide on Wednesday.
  • Casey closed his Boise State career with 41 consecutive starts at left tackle in 2024 and 2025.
  • The 2026 NFL Draft is scheduled for April 23-25 in Pittsburgh, Pennsylvania.

What they’re saying

“Casey is a determined, assignment-sound blocker and plays to his strengths to work around some of his physical shortcomings. He projects best on the interior and should compete for meaningful snaps during his rookie season.”

— Dane Brugler, Draft Analyst, The Athletic

“I'm not a huge fan of Boise State's Kage Casey as an NFL offensive tackle. Too much leakage around the arc and to either side (when playing left tackle). But put him in more of an enclosed space as a move/power guard, and I think you've got something.”

— Doug Farrar, Draft Analyst

“Well-proportioned, durable tackle prospect who counters his lack of length with persistence that helps him finish the job. Casey is a capable athlete with enough range to reach zone landmarks and the body control to redirect when mirroring edge-to-edge.”

— Lance Zierlein, Draft Analyst, NFL.com

What’s next

Casey will look to impress NFL teams during the pre-draft process, including at Boise State's pro day and any private workouts. The 2026 NFL Draft is scheduled for April 23-25 in Pittsburgh, Pennsylvania, where Casey will hope to hear his name called in the middle rounds.

The takeaway

Kage Casey's evaluation by NFL draft experts highlights the importance of versatility for interior offensive linemen in the modern game. While he may not have the ideal physical tools to excel at tackle, his strong fundamentals and athleticism could make him an attractive mid-round option for teams seeking a guard or center who can contribute early in his career.
