#6 Bob Backlund (648 days)

The start of the reign: In February 1978, Bob Backlund became WWE champion for the first time when he defeated Superstar Billy Graham at MSG.
The end of the reign: This is where things get complicated. In November 1979, Antonio Inoki won the title from Backlund at a house show in Tokyo, Japan, ending his spell as champion at 648 days. However, Inoki’s reign lasted just six days and WWE does not officially recognise this as a title change in some of its records (but we do!).

#5 Pedro Morales (1,027 days)
The start of the reign: In February 1971, Pedro Morales ended Ivan Koloff’s 21-day reign as champion at MSG to begin his legendary 1,027-day tenure with the title.
The end of the reign: With Morales closing in on three years as champ, he was defeated by Stan Stasiak at a Philadelphia house show in December 1973. Stasiak, the very definition of 'transitional champion', only held the title for nine days before losing it against the next man on this list.
