Background

Kage Casey grew up in Happy Valley, Oregon, and attended Clackamas High School, where he played offensive tackle and defensive end, wrestled, and by his own account had never thought about playing college football until his high school coach inspired him before his junior season. A three-star recruit ranked No. 8 in Oregon, he signed with Boise State over Oregon State in 2022 and redshirted his first year. He earned Second-Team All-Mountain West as a redshirt freshman in 2023 and then started every game for the next two seasons, earning back-to-back First-Team All-Mountain West at left tackle in 2024 and 2025. In 2024 he helped pave the way for Ashton Jeanty's record-breaking season of 2,601 rushing yards and 29 touchdowns as Boise State set a school record with 3,365 team rushing yards, won a second straight Mountain West title, and reached the College Football Playoff for the first time in program history. He closed his career with 41 consecutive starts at left tackle. He took part in the Senior Bowl and declared for the 2026 NFL Draft.

Physical Attributes

Casey is an extremely middling athlete. I would not describe him as fast or slow. Strong or weak. Balanced or unbalanced. Good lateral quickness or poor. Just pretty straight down the middle in everything. Without overwhelming size either, Casey is firmly in my not a tackle category.

Data and Tape Analysis

As mentioned above, Casey is going to have to slide inside to guard in the NFL. The radar chart above is solid, but belies the fact that he played the worst competition of any college OT we will look at in my prospect profile series. So when you look at that, remember to bring all the points in a bit. And more importantly for my personal analysis, if you are playing at a lower level and the radar chart is not anything other than stunning, it's a long road to hoe.

One of the main reasons Casey has to move inside is his inability to deal with speed on the outside. Across his schedule this year, there was maybe one guy who will be drafted over the next two years on opposing lines, and he could handle even that level of speed. Though if he can more easily ID and expect the player across from him to come directly at him, if not a little off, he will withstand much better.

The same goes in the run game. His movement skills are poor, and he has a hard time identifying who to block when there are multiple people it could be, so he is a gap scheme player. Go hit, and try to do it as a part of a double team, because otherwise, you are not getting much movement. His hands are also weak in this area, exacerbated by short arms, where he cannot impose on defenders really at all.

Grade and Outlook

Kage Casey looks to be IOL depth for whoever drafts him. Turning 23 in season, I can't imagine that he has unrealized upside either. Though he did not get the best nutrition, weightlifting, and coaching while at Boise, so I will say there might be a little more than I think.

Grade: 3.9 (Late 4th Rounder / Early 5th Rounder)
