With the Steelers major offseason acquisitions done with, the 90-man roster appears to be set. Looking over the roster, there are the obvious starters and backups who make up the majority of the in-season roster. There are typically about 5-8 spots that are up for grabs, where a relatively unknown player or UDFA has a chance to shine and find their way onto the active roster.
Take Fred Johnson and Tuzar Skipper last year: both players shined in the preseason as UDFAs and ended up on the Steelers active roster (although both were eventually cut).
