Green Bay Packers RB Eddie Lacy worked out with P90X founder Tony Horton after the season, and Horton estimated Lacy lost 15 to 20 pounds during the workouts. Running backs coach Ben Sirmans said this week that Lacy might again work with Horton leading up to training camp. ‘I’m hopeful,’ Sirmans said. ‘The information I got from what people have told me, it’s helped him. So you always want to be able to do things that help people. I hope he’ll do it.’ After offseason workouts, head coach Mike McCarthy said Lacy still had work to do.
