Pittsburgh's front seven has been transformed over the last few years into a young, athletic unit. In 2015, they have the potential for greatness -- but can that potential be realized? In 2014, the well ran dry for much of the season. In 2015, it might be a gusher.
Lawrence Timmons: 2007 first-round draft pick. Seven-year starter, has led the team in tackles most of those years. 2014 Pro-Bowl linebacker.
Bud Dupree: 2015 first-round draft pick (is anyone else seeing a pattern here?).
James Harrison: From undrafted free agent to the 2008 NFL Defensive Player of the Year, and a generally surly beast on the field.
