Rob sat backstage trying to relax after the hectic workload the weekly show brought to the table. While he wasn't a backstage worker or supervisor anymore, he wasn't having an easier time either.
Being on commentary meant, Rob had to pay attention to the show throughout the 90 minutes without any break. He has to be ready to jump in when something goes wrong inside the ring and take away the audience's attention from the mistake.
Luckily, the new way of commentary by Dallas and Rob did help in this a lot.
Typically, when the live broadcast was happening, it was neither the crowd in front of whom they were wrestling nor the personnel that was overseeing who saw the mistake first.
It would be the audience watching at home. Being given a close seat to the going ons inside the ring, they would be the first to pick up on a botch or call out the mistake.
