If the Pittsburgh Steelers are set on keeping five safeties on the roster again, as they did out of training camp last season, then it would seem that they have a budding competition on their hands.
By the end of the season, of course, the Steelers actually ended up carrying six safeties on the 53-man roster due to the fact that they needed a temporary replacement for Shamarko Thomas on special teams.
Ross Ventrone was called up from the practice squad to fill that role, but he played so well in that capacity that the coaching staff never found the justification to send him back down, even when he himself was injured, missing two weeks if I recall correctly.
