The Bears replaced one turnover prone quarterback for another. According to Ian Rapoport, the Bears are expected to sign Mark Sanchez. At this point, I would think Sanchez would probably be the backup to Mike Glennon, or at least compete for that backup role.

The #Bears are expected to sign former #Cowboys QB Mark Sanchez, source said. They are finalizing a deal. More depth to the QB room.
