One of the reasons Baltimore opted not to sign free agent quarterback Colin Kaepernick earlier this offseason was because the Ravens did not have a need for anything more than a camp arm. Despite the fact that Kaepernick, according to someone close to him, would have been interested in that opportunity, the Ravens cycled through a group of third and fourth stringers over the last two weeks in Vaughan and David Olson. Now, Lewis joins a group that includes backup Ryan Mallett, Liberty product Josh Woodrum and the injured Joe Flacco (back).
