#1 SmackDown will be dominated by a trio for the next year

Given how things were going before WrestleMania 36, it was clear that the two most prioritized stars are Roman Reigns and 'The Fiend' Bray Wyatt. It made sense since Reigns is still popular in a large demographic while Wyatt has been the most consistent and entertaining character on WWE TV over the past 11 months.
Braun Strowman becoming the Universal Champion has added him to the top mix, and the World Championship picture on SmackDown will be dominated by three men - Strowman, Reigns, and Wyatt. They're the right picks as well and even if there's a major draft that comes into SmackDown soon, we don't see them taking up one of those spots.
Bray Wyatt challenging Braun Strowman could simply be the start of a year dominated by the trio of top-tier stars. It's going to be interesting to see how all of it progresses and who comes out looking strong.
