The Green Bay Packers offseason program was going to be pushed back due to their Super Bowl run, but I didn't know the exact timing of it all. In this time last year, the players had been tendered their contracts as restricted free agents, and some had signed and began the offseason strength and conditioning training, along with the players already under contract.
According to the Press-Gazette, the typical mid-March strength and conditioning training was postponed to early April because of the Super Bowl. So as of this moment, the lockout hasn't interfered with their preparation for 2011. Of course, the owners and players are still far apart, so it's not going to stay that way. From Rob Demovsky:
But the lockout will almost certainly wipe out at least one of the two phases of McCarthy’s spring plan. He had planned to pick up the program early next month in phase two, which is a combination of strength training and individual football drills, and then transition into the typical organized team activities and minicamp schedule in May and June.
