Can Steelers' defense take next step?

New Steelers defensive coordinator Patrick Graham spoke to the media for the first time today. Can the Steelers’ defense take the next step this year and actually preform like the highest paid unit in football? Mullsy thinks Patrick Graham’s defense in Las Vegas last year was unfairly evaluated due to how bad their offense was. The Steelers were 17th in scoring defense last year despite being the most expensive unit in the entire league. Mullsy also thinks that Graham did not have very much to work with regarding his defense in Las Vegas in years prior. The Steelers were probably too reliant on turnovers in years prior.
