ST. LOUIS — Frank Cignetti paid the price for the failures of the St. Louis Rams’ offense.

There’s not much time left for his successor to pick up the pieces.

The Rams, next to last in offense in the NFL and last in several key categories, fired their offensive coordinator Monday. Rob Boras, assistant head coach/offense and tight ends coach, will take over the coordinating duties.

Coach Jeff Fisher said Monday he was making the move now thinking about the future of the franchise. He’s in his fourth season and yet to field a winning team with St. Louis (4-8).

“All the blame’s not to fall on his shoulders, but that’s the way this business works,” Fisher said, adding players should also shoulder responsibility.

“Everybody contributed,” the coach added, “but we have to move in a different direction.”

Fisher said he’d been thinking of making a change for a few weeks. He said he hadn’t told Cignetti , a former Pitt offensive coordinator, until relieving him of his duties at about noon Monday, then told the players about two hours later.

“I’ve looked hard at it over the last couple weeks,” Fisher said. “We’re getting what we want out of them on the practice field and it’s not carrying over to the game.”
