With the lull of the NFL offseason in full effect after the draft, many football fans can only read up on the OTA’s or count the calendar days until training camps get under way for their favorite ball clubs. For the Pittsburgh Steelers, it’s a team in transition as they’re undergoing a defensive overhaul, saluting goodbyes and well wishes to all-time fan favorites like Troy Polamalu or Brett Keisel. On offense, it’s the same story, and it’s been occurring for a few years now, morphing from your grand daddy’s Steelers, a smash mouth, ground-it-out, ball control offense to a juggernaut capable of scoring with the best of them, and littered with Pro Bowlers.
