Details of Gus Malzahn's new seven-year, $49 million contract extension at Auburn are still being hashed out, but it is "definitely not" fully guaranteed. Auburn president Steven Leath addressed Malzahn's contract and other athletics issues with reporters after introducing Allen Greene as the program's new athletic director on Friday. "We actually haven't signed (Malzahn's contract) either," Leath said. "We're still working through the final details. I'm still a trust guy and Gus and I are functioning well together. We know the basic tenets, we've drawn things up, sent it to his attorney. We'll get that cleaned up pretty soon." Leath could not recall the exact percentage but said "it's above 50, but well under 100." Asked again that the deal is not fully guaranteed, Leath said "it is definitely not."
