Aaron Rodgers’ favorite wide receiver says it doesn’t even feel like he’s left yet.  Jordy Nelson was in Lake Geneva last weekend for the Jockey Being Family Gala and Golf Classic at the resort.  After 10 seasons in Green Bay, he was released by the Packers and quickly signed by the Oakland Raiders.  Nelson philosophically says it’s just “part of the business.”  Several of his former teammates were among the celebrities at the event.  The Packers started organized team activities Monday.  Nelson’s new team, the Raiders, begin O-T-As today (Tuesday).
