WWE pay-per-views don’t just come together in improvised fashion. Instead, each piece needs to be systemically arranged to tell their stories in the ring. It’s not like they’re allowed to just go out there and have a good match.
Superstars needed to rehearse for Summerslam, but because of how busy everyone is they had to make time during different times of the day. Brad Shepard reports that Friday was that day for WWE Superstars as rehearsals were going on throughout the entire day.
According to a source in #WWE, segment rehearsals were going on all day Friday.
Hopefully, Vince McMahon won’t change too many things around because it kind of defeats the purpose of rehearsals if that’s a possibility. It’s still good to know that the company is preparing their Superstars for the big day.
