Building the 53-man roster is a never-ending process, which continually evolves throughout the season as needs emerge and opportunities become available, but there needs to be a starting point. The Pittsburgh Steelers reached their initial starting point just minutes ago, but that means 37 people who spent time with them are currently out of a job (or 36, actually, since quarterback Joshua Dobbs was placed on the Reserve/Injured List).
15 years into the process, head coach Mike Tomlin recently talked about how it never gets any easier to have those conversations when you have to inform a man that they are not going to have a job, and, worse still, that their dream may well be over, unless you can find another opportunity elsewhere.
