Bradford chairman Peter Hood has apologised to fans for the club's poor season in Super League.
The Bulls missed out on the play-offs for a third straight year, winning just nine of their 27 games, despite bringing in new head coach Mick Potter.
Keith Lulia and Luke Gale are two of the signings for the 2012 season as the Bulls aim for an improvement.
"I want to acknowledge the pain every fan is feeling because 2011 was a very poor season," Hood said.
In a more successful period, Bradford reached five consecutive Grand Finals up to 2005.
Ten new signings under Potter in the last year failed to revive performances on the pitch as the club cut season ticket prices to improve match attendances.
"Some of our performances simply weren't quite good enough," added Hood. "Those dropped points made all the difference at the business end of the season.
"But a few of the losses were very bad indeed, not just in terms of the result but also in terms of the way those games were lost, and that is unacceptable. We need to fix things up and we will.
"The re-signings and new players coming in for 2102 and other changes planned are designed to get us up the table, into a play-off spot and pushing for the top six."
