Let’s face it, some people get a lot more excited about undrafted rookie free agents than others. A lot of people who fall into the former group end up coming to sites like ours, because the average fan doesn’t even know who they are, and might not even be sure of what an undrafted free agent is.
The Pittsburgh Steelers had a slightly smaller group of undrafted free agents than normal because their roster was more filled out than it is typically, but they were able to add more to go over 90 for multiple reasons, including Christian Scotland-Williamson’s exception, Ryan Shazier having been moved to the PUP List, and others.
