The Packers continue training camp workouts heading into the weekend. One battle that people will have their eyes on is at cornerback where Sam Shields and Jarrett Bush are battling for a potential starting spot. With Charlie Peprah cut on the eve of camp, the battle for a starting spot at safety will come down to 2nd year man MD Jennings and rookie Jerron McMillian. Jennings was running with the first team on Thursday. Charles Woodson also lined up at safety on Thursday. On the other side of the ball, the Packers were one of the NFL’s best last season, but Aaron Rodgers says they can still improve. The Packers have practices that start at 8:15am today and on Saturday before taking Sunday off. Saturday’s practice is the first one in full pads.
