Pittsburgh's receiving corps experienced a huge letdown in 2012 as pending free agent Mike Wallace and emerging stars Antonio Brown and Emmanuel Sanders all took a giant step backward during the season.
Wallace, who's protracted holdout alienated the fanbase, became a player with almost zero effort who dropped easy passes and big-play balls alike.
Brown, who signed a nice extension before the season, became drop-prone as well and made some serious mental errors down the stretch on punt returns and on offense that led to losses.
Sanders simply couldn't get on track, but emerged from the season as the most consistent of the team's receivers.
In 2013, the Steelers must help Ben Roethlisberger by coaching the mistakes out of Brown and Sanders, replacing Wallace with free agent Plaxico Burress, who needs a bigger role out of the slot and in the red zone, and once again, involving possession receiver Jerricho Cotchery in the system.
