I always see it noted that Ted Dibiase was a huge failure as a manager. What were the major issues that led to him being such a disappointment in that role? 
He associated with losers who always lost, he never had any particularly good babyface foils for his evil in the same way Bobby Heenan had Hulk Hogan, he could never get physically involved due to injury, his whole gimmick was that he was a millionaire but he dressed in a friggin' sweatsuit.  That's just off the top of my head.
