According to a new report from PWInsider.com's Mike Johnson, one of the reasons why WWE seems to be hesitant to push Braun Strowman to the next level is because he has some heat with WWE officials backstage.

Although WWE officials are generally pleased with his performances, he sometimes upsets people backstage by not adhering to certain backstage etiquette. Specifically, he reportedly has a tendency to show up late and/or leave shows early.

Johnson reported the following (via WrestlingNews.co):

"One of the things that I heard from multiple people — we’re talking four different people. There are times where Strowman is negligent when it comes to showing up on time.

“He has a reputation at times for leaving a little early and sometimes he makes mistakes in terms of etiquette backstage in the locker room. Sometimes, as one person put it, ‘He’s his own worst enemy and his worst advocate.’

“They would be high on him and just when he gets to the point where you would think the next step is putting him into the centerpiece position for the company, [then] something happens and he makes some sort of misstep backstage and people within management kind of cool on him and they take a step back.”
