Getting to know the Steelers 2025 UDFAs: Blake Mangelson

After the Pittsburgh Steelers selected seven players in the 2025 NFL draft, they continued adding to the roster by coming to terms with seven undrafted free agents (and later added an eighth). With many draft profiles focusing on those players towards the top and middle of the NFL draft, it is time to get to take a look at these other members of the Pittsburgh Steelers who will have just as much opportunity to make the roster in 2025 as those who were selected in the draft, despite the more difficult path.

Remember, some draft profiles for these players are quite harsh as they are looking at them as a draftable prospect. Taking a flyer on an UDFA is a completely different story as many times the potential the player shows is what lands them on an NFL offseason roster.

Next up is defensive tackle Blake Mangelson from BYU.
