After five straight losses that have derailed their season, the Pittsburgh Steelers coaching staff is expected to undergo a considerable makeover this offseason, a source close to the situation told ESPN NFL Insider Adam Schefter.

Changes are expected with Pittsburgh's special teams coach Bob Ligashesky, amongst others.

Other coaches that could be in trouble in Pittsburgh include offensive coordinator Bruce Arians and offensive line coach Larry Zierlein.

Only one other Super Bowl champion lost five in a row the following season, and the 1987 Giants deserve an asterisk because they used replacement players during part of that strike-interrupted season.

What most troubles the Steelers is who is beating them.

A year ago, the Steelers survived one of the toughest schedules in NFL history to win their sixth Super Bowl, facing the Eagles, Ravens (twice), Chargers, Giants, Cowboys, Colts, Patriots and Titans during the season.

This season, their losses to the Browns (1-11 at the time), the Chiefs (2-7 at the time) and Raiders (3-8 at the time) rank as three of the biggest upsets in the NFL all year.

The Browns were last in the NFL in total defense and were playing without five injured starters -- in essence, they were using their replacement team -- yet they held the Steelers without a touchdown and sacked Ben Roethlisberger eight times.
