In news that’s not at all surprising, the Saints have had a preliminary discussion with Rafael Bush‘s camp about prolonging the safety’s stay in New Orleans, a league source said Tuesday. The Saints have two options to retain Bush, a restricted free agent: They can tender him by March 11, which would give them the right to match any offer he might get from other teams; or they could sign him to a long-term deal. The lowest tender Bush could be offered would be about $1.3 million, the source said.
