I think they call in the "Offseason Conditioning Program"...basically, they're asking all players under contract to come in and meet the new coach, and the new strength coordinator. The object is to get the players into a new workout schedule, and let them know about the training camp schedules and such. And meeting as a team could be a good thing. Get the pep talk from the new coach, and learn a little about his style.
Manny Wright is expected to attend.
Olindo Mare and Jay Feely are also expected to attend. Odd? Maybe.
