#2 Nobody really benefits from winning the match
Some could make the argument that someone like Andrade could have won the match and launched his career to the next level. Others could say something like Luke Harper could have won the match and established himself as a legitimate top star. Ultimately, someone like Jeff Hardy could have created a really great feel-good moment.
Look at someone like Mojo Rawley. Even if he won the Andre the Giant Memorial Battle Royal, it did nothing to further his career and he can't even get TV time anymore. And therefore, your argument is invalid.
And this is why Braun Strowman winning the match is not a death knell for someone else, in my personal opinion. If anything, it's someone deserving of a win getting pushed and getting his due. Maybe the rest of the night will be full of surprises for the WWE Universe.
