Running backs coach Skip Peete said Marion Barber has dropped about 10 pounds from last season, when the Cowboys listed him at 222 pounds. According to Peete, Barber dropped the weight in addition to regain lost speed. ``He's leaner and looks quicker than he's been,'' Peete said after Tuesday's Organized Team Activities workout. ``It's noticeable. I'm excited to see what he does when we get to camp.''
