If Favre is retired, then it is best he get on with it so that the team can fill his spot on the roster with another player. If he's not retired, then they need to know so they can either get him into camp or cut him (which could be a PR nightmare in Green Bay). If only coming back if someone is hurt and the Packers need him, then go ahead and file retirement papers. You can unretire and sign a short-term contract later if the situation arises. In the meantime, you have to make things clear for the Packers so they can plan accordingly.
All they have to do is put him on the reserve-retired list. That allows them not to pay him, and he doesn't take up a roster spot.
