Steelers Steal Big Undrafted Free Agent From Vikings After Originally Agreeing To Terms

   

Since the conclusion of the 2025 NFL Draft, the Pittsburgh Steelers have continued to strengthen their roster through the signing of undrafted free agents. Pittsburgh went into the event with a commitment to bolster their trenches, drafting defensive lineman Derrick Harmon with their first-round pick. On Monday, the Steelers agreed to terms with Blake Mangelson, a defensive tackle from BYU. Mangelson will bring additional muscle to Pittsburgh's line and is a promising prospect, considering he only got better throughout his time in college. Although those unfamiliar with Mangelson may be quick to dismiss him due to the rookie going undrafted, there are plenty of stats that should give Steelers fans confidence in the lineman's abilities.

During his time with the Cougars, Mangelson earned some memorable accolades, including a defensive MVP Award. It's easy to see why the young player's stock has been rising so quickly. At BYU, Mangelson got more and more tackles every season, getting just five total tackles in the 2021 season, but 37 in the 2024 season. Mangelson's stats also improved in other areas, including sacks and interceptions. Some of Mangelson's biggest strengths as a defender are as a pass rusher and batting down passes.
