Pittsburgh Steelers quarterback Ben Roethlisberger has never before in his career been without a veteran backup. The day he was drafted, he had Charlie Batch to consult with, and I think most who follow here regularly know the story of the role that Batch played in his maturation.
Roethlisberger pretty much had Batch from his rookie season through the 2012 season, at which point the Steelers drafted Landry Jones, but at the same time they also brought in Bruce Gradkowski to fulfill the role of that veteran presence.
