'EJ Manuel and Cardale Jones both struggled in the practices open to the media. Manuel threw multiple pick-sixes and was hesitant in 7-on-7 drills, a familiar sight. Jones unleashed one eye-popping throw deep, yet floated several passes high and short in addition to footwork problems in other drills. One play, he smashed into his fullback. Jones is clearly a project. Granted, a lot of teams would be waving the white flag if their starting QB went down but the back-up plan is especially worrisome here in Buffalo.'
