STM Take
Rookie tier 8 (#100) at the bottom of the IOL rotation band for a 4th-round pick is on the year-one band for Day 3 prospects. The Iowa Big Ten technical foundation plus 36 college starts give him basic developmental floor. The 2026 question is whether Colby crosses into tier 7 territory in his year-two jump or whether the role compresses back to practice-squad depth.
Colby came out of Iowa as the San Francisco 49ers' 4th-round pick (113th overall) in 2025 after starting 36 games for the Hawkeyes across multiple interior positions. The 49ers used him in the rotation as a rookie as part of the broader offensive line transition. His first STTM appearance comes in 2025 at tier 8 (#100), the bottom of the IOL rotation tier band.
Strengths
- Iowa Big Ten 36-start positional flexibility across all three interior positions gives him roster versatility that few late-round rookies carry.
- Year-one rotation snaps for the 49ers at age 22-23 gives him the structural developmental reps.
Concerns
- Rookie tier 8 (#100) at the bottom of the rotation band caps the year-two ceiling expectations.
- San Francisco's broader offensive line investment (Brendel, Puni, multiple Day 2 picks) compresses the structural role for Colby.
What to watch: Whether Colby holds active-roster reps for the full 2026 season or whether the role compresses to practice-squad rotation.
