Aidan Keanaaina wasn't selected in the 2026 NFL Draft, but the Detroit Lions made sure he didn't stay on the board long. In a move that signals serious intent, Detroit guaranteed the former California Golden Bears defensive tackle $300,000—a rare financial commitment for an undrafted free agent and a clear message that they see him as more than just a training camp hopeful.
Keanaaina's path to the NFL is a story of steady growth and relentless power. After a quiet start at Notre Dame, where he managed just 11 tackles across multiple seasons, he transferred to Cal and quickly became the anchor of the defensive front. In 2024, his first full season with the Bears, he started all 13 games and racked up 45 total tackles, 2.5 tackles for loss, one sack, and a quarterback hurry. Those numbers are particularly impressive for an interior lineman, whose primary job is often to eat up blockers and let the linebackers clean up.
He followed that breakout year with another strong campaign in 2025, posting 56 tackles and 1.5 sacks. Over his collegiate career, Keanaaina amassed 111 total tackles and three sacks—stats that might not wow casual fans, but they tell the story of a player who consistently controlled the line of scrimmage and played a high-volume, high-impact role in the trenches.
One of his standout moments came during the 2024 season, when his interior presence helped Cal's defense hold its own against top conference opponents. Keanaaina's ability to absorb double teams and still make tackles made him one of the most reliable run defenders in the ACC. That performance earned him an honorable mention all-conference selection and a strong 79.0 grade from Pro Football Focus, ranking him among the top returning defensive tackles in the conference.
At 6-foot-3 and roughly 320 pounds, Keanaaina fits the classic mold of an NFL nose tackle—a big-bodied, powerful force designed to clog running lanes and demand extra attention from offensive lines. The Lions' willingness to invest guaranteed money in him suggests they believe he can do exactly that, and maybe more, from day one.
For a player who went undrafted, Keanaaina now has a golden opportunity in Detroit. If he can translate his college consistency into NFL production, the Lions may have found a hidden gem in the defensive interior—a player who plays with the kind of disruptive energy that makes offensive coordinators lose sleep.
