The Facts: The Raiders have announced, via Twitter, that they have signed Boller.
Diehards Line:Boller spent the 2009 season with the Rams, after spending 2008 on injured reserve with the Ravens. In all, Boller was in Baltimore for six years. He started 42 games over five seasons, including all 16 in 2004. As PFT's Mike Florio suggests, in Oakland, he'll presumably compete with JaMarcus Russell and Bruce Gradkowski for the starting job. ... Worth noting: Boller's final year in Baltimore was also Raiders offensive coordinator Hue Jackson's first of two years with the Ravens.
