LA Knight is First of Many Filler Challengers for Roman Reigns2 of 5Kevin Sebatis/WWE via Getty Images LA Knight and Roman ReignsPost-SummerSlam, it looks like Roman Reigns will stick around to defend his World Heavyweight Championship. LA Knight makes perfect sense, especially after winning against The Usos and Jacob Fatu at SummerSlam. However, Knight has no chance to win. While there may still be a time for him to win big, that does not look like a close reality. WWE wants Reigns at the headline act for many big shows to come, but the only place the company will truly set up a changing of the guard would be at The Show of Shows.
