The Buffalo Bills give them a run for their money in that regard. The most recent addition is their waiver claim of former Steelers sixth-round pick Justin Brown.
Kraig Urbik, Doug Legursky, Corbin Bryant and Stevenson Sylvester are but a few former Steelers now or just recently with Buffalo.
Brown was the winner of a mildly competitive battle for the Steelers' last receiver spot heading into the 2014 season. He was moved from outside to the slot, and started the season as the team's slot receiver, getting early playing time over veteran Lance Moore.
Brown eventually fell out of favor right around the time rookie Martavis Bryant began playing. Moore overtook him on the depth chart, leading to Brown's release.
He had 12 catches for 94 yards in his second season in the NFL. He spent 2013 on the team's practice squad.
Moore has also recently asked for his release, setting up a battle of unknowns for the team's last wide receiver position or positions. Antonio Brown, Markus Wheaton and Bryant are set as the team's main receivers heading into 2015.
