The Undertaker vs Rusev (Casket Match)

Why has WWE changed this match up 2 times in the last 10 days? I mean, does it even matter who the Undertaker is facing in the WWE right now? Unless your name is Brock Lesnar or Roman Reigns, the chances of you defeating The Undertaker are same as the reaction 'Mania's main event got - zero. Poor Rusev, despite being the most over superstar on the roster, will once again be taking a loss this Friday.
Taker's match against John Cena, WWE's biggest box-office draw, at 'Mania 34 lasted a mere 2 minutes and 46 seconds. Hence, it won't be a shock if this match ends even before hitting the 2-minute mark. WWE is building Taker back as the resurgent legend before he finally clashes with Cena again at 'Mania 35. As for Rusev, he is now the official jobber to all the megastars of the company.
