The 30-year-old offensive guard won two Super Bowls with the Giants, one of which as the team's starting left guard. Boothe had his best season in 2012 which was his only full season at left guard.
The 6-5, 300 pound Boothe was selected by the Raiders in the sixth round of the 2006 draft out of Cornell. He spent just one season with the team, starting 14 games at right guard. Despite his play as a rookie, he was release prior to the start of the 2007 season and was signed by the Giants. He was a reserve offensive lineman for the Giants for three seasons before finally becoming a starter late in the 2010 season.
Boothe's addition bolsters a group that was in dire need of help at left guard. He becomes the second outside free agent offensive lineman signed this off-season, and the third attempted signing with the Roger Saffold deal falling through to begin free agency. The Raiders also signed New York Jets former right tackle, Austin Howard.
