Live around 5 p.m., Post-Gazette sports columnist Paul Zeise reacts to a report from Steelers insider Gerry Dulac that coach Mike McCarthy is close to naming former Raiders DC Patrick Graham to the same job in Pittsburgh.

How suited is Graham to taking over the Steelers' unique 3-4 scheme? Will it look similar to how it did under Bill Cowher and Mike Tomlin? Or will Graham put a unique spin on it? And how much room does this unit have for improvement, as it's led by names including T.J. Watt, Cam Heyward, Jalen Ramsey, Alex Highsmith, Joey Porter Jr. and others?

Paul tackles those questions and more as McCarthy continues to build his staff.
