After stints with the Baltimore Ravens and St. Louis Rams, QB Kyle Boller is back on the left coast after signing with the Oakland Raiders today. Boller becomes the Raiders third QB on their roster, joining expected starter Bruce Gradkowski and former #1 over draft pick JaMarcus Russell. What Boller's role and where he will be on the depth chart remains to be seen. Perhaps the relationship with former Ravens QB Coach Hue Jackson had something to do with it, as reported by The Baltimore Sun's Jamison Hensley on Raven Insider.
