You'll be well aware of the significance of this number, but it really does need celebrating as one of the most spectacular facts from CM Punk's WWE career. The 434 days he reigned as WWE Champion is a record in the modern era. You have to go all the way back to John Cena's 380 days as champion in 2006 / 2007 to even get close. Then you need to go all the way back to Hulk Hogan's 1,474 day reign that started in 1984. Not since that Hulkamania reign had anyone been champion as long as Punk managed. It is a legacy that will endure for a very long time.
