Saints signed TE Daniel Graham. The Saints made a flurry of roster moves Saturday, signing undrafted free agents DB Nick Hixson and G Paul Fenaroli while waiving LB Nate Bussey, DB A.J. Davis and G Andrew Tiller. Graham appeared in all 16 games for the Titans last season, but as a pure blocker, notching only two catches. He'll provide insurance for David Thomas, who is working his way back from a concussion-marred 2011.
