Free agent Lofa Tatupu's recent visit with the Saints had some league observers scratching their heads and wondering if the team might be mulling the option of adding a cheap replacement for Jonathan Vilma this offseason, but we're hearing it was more a case of the team just doing its due diligence. A major shakeup at middle linebacker appears unlikely at this point. Tatupu, who sat out all of last season after the Seahawks accommodated his request to be released, has a history of knee injuries and concussions and it's believed that the Saints did not make him a contract offer when he met with team officials in New Orleans. The Saints are hoping that getting some rest this offseason will allow Vilma to return stronger in 2012 after he was hampered by knee problems throughout last season. He missed five games after undergoing surgery on the bad knee, but observers say he never appeared to be 100 percent even when he returned.
