Ian Rapoport of NFL Network reports that the Packers want Lacy to lose 30 pounds, and Lacy is committed to accomplishing that before the season starts.
Lacy weighed 231 pounds at the 2013 Scouting Combine, and the Packers liked him well enough at that weight to choose him in the second round of the NFL draft. He’s only listed at 234 now, but he surely weighs significantly more than that. A good guess would be that Lacy currently weighs more than 250 and that the Packers want him under 230.
Ultimately, what the Packers really want is for Lacy to play like he did in his first two seasons, and not like he did in his third year, when he had career lows in carries (187), yards (758), yards per carry (4.05), touchdowns (three), catches (20) and receiving yards (188). The Packers’ coaches think the key to getting Lacy back on track is to get him in better shape.
