There's actually an odd amount of symmetry with the Series wins - the Hawks have won two championships under each owner. Each set of championships under a particular owner were won by the same manager (Nankai - Kazuto Tsuruoka, Daiei - Sadaharu Oh, Softbank - Koji Akiyama). Half of the Hawks' championships have come from defeating the Tigers - one time for each owner (Nankai in 1964, Daiei in 2003 and Softbank in 2014). The amount of time between each owner's championship is progressively getting shorter - 5 years for Nankai, 4 years for Daiei and 3 years for Softbank. So if these trends keep up, the Hawks will not win another championship until they are sold to another owner. Once they win for their new owner, they'll win again two years later by beating the Tigers.
