#4 To sow the seeds of discontent between Strowman and Rollins
How do you make two babyfaces build heat for their clash? There's obviously a professional rivalry between the two individuals, but is there a compelling reason for the two men to clash with full gusto in the main event of the night? Booking this loss was a great way to overcome the lack of storyline heat.
Not only was there a misunderstanding of sorts between the two men leading to the loss, the fact that Rollins was responsible for Braun Strowman losing his title must also weigh heavily on him. Now suddenly there's a reason for the two men to clash with utmost intensity because the last thing you want to do is make a monster angry even if you are Seth Rollins.
Hence, Robert Roode was a tactical component in telling a long term story, a genius move from Heyman and of course, Vince McMahon.
