In what has to be characterized as a minor surprise, the Steelers are apparently set to ink DE Brett Keisel, 30, to a long-term contract extension. Maybe the fact that it’s difficult to find ends that can thrive in Pittsburgh’s 3-4 scheme played a role in the decision. Or maybe it’s that Keisel is Ben Roethlisberger’s best friend on the team. But I expected PK Jeff Reed or S Ryan Clark to be next in line for an extension — not Keisel.
