Look at that huge crack on the right hand side. That crack was caused by the devastating weight of a black silk-like cover. In the end they weren't even used. Dean Ambrose lay Seth Rollins' head on top of them before being granted his WWE World Heavyweight Championship match, which begs the question why real ones weren't used. Legitimacy and all that... Shouldn't the business be trying to look as 'real' as possible. The company had similar problems back when Ambrose himself was injured by Rollins which shows they certainly didn't learn from their mistakes.
