He runs a 3-4 defense and therefore would have been a good fit for Miami.
Al Groh, meanwhile, still hasn't been hired as defensive coordinator at Georgia Tech, so he remains an option. He's also got a history with Parcells and has experience running a 3-4 defense.
This brings us to the new candidate, Pittsburgh Steelers linebackers coach Keith Butler. He is scheduled to interview for the position with Coach Tony Sparano.
Butler would seem like a good candidate even though he's never been a coordinator in the NFL based on the success of the Steelers' 3-4 defense in his seven seasons with the team, in particular the work of his linebackers.
Butler, who played 10 seasons with the Seattle Seahawks, coached Joey Porter for four seasons with the Steelers.
