Can a player simply retire and then un-retire and sign with any team? We have seen that happen with Favre last year and possibly this year as well. Green Bay didn't receive any compensation last year when the Jets signed Favre and I don't think New York would receive compensation if the Vikings ink him this year. So my question is what happens if a franchise player like Julius Peppers files his retirement papers and then decides to come back (without missing a season)? Can he then sign with any team without compensation to Carolina?
