#4. AJ Styles becomes a 3-time WWE Champion
AJ Styles will always be a reliable pick and a loved WWE Champion. Admit it, whether you think it's the best decision or not, you're likely not going to find a lot of fan backlash to AJ Styles becoming WWE Champion.
After all, he's had two great reigns, the second of which saw him be WWE Champion for over a year (joining an elite list in the process). Styles has been in one Chamber match before, and that saw him go all the way till the end until Bray Wyatt eventually eliminated him to win the match.
It wouldn't be surprising to see WWE put the title on Styles so that his match against Randy Orton at WrestleMania 35 can be a high-profile one. Either way, the match honestly doesn't need the title at all to have a big-match feel to it. They are two big stars, after all.
