This was not a mistake. This builds interest in the product, not only are people going to be more attuned to what is going on on TV now, but tickets to the house shows are going to sell better now because there is the thrill of missing a title change.Fair enough, but at the same time people want to be able to see title changes, especially in this day and age. Was there even a camera crew there so they can throw the match on the Network some time later? If not, then this was a huge mistake on the part of WWE/NXT, injury or not.
Either way, this is surprising. I remember hearing they were planning to call up Joe after WrestleMania. I guess they decided to hold off for some reason.
This happened all the time back in the 80s. Arguably the greatest period for WWE as a business.
