6. Rey Mysterio and Sin Cara
We've got to have a storyline for Rey Mysterio going into WrestleMania, and it's not too early to set the stage for The Grandest Stage of Them All. Rey should be in a feature match at 'Mania: he has had so many injuries that his abilities in the ring are waning. For the sake of his own physical well-being, this needs to be his last run, and he deserves all the hoopla that would accompany a WrestleMania retirement. Let's do it right. From the standpoint of lucha mask tradition, it makes the most sense for Rey to face another masked wrestler. After decades of honoring and fighting for his mask, having a mask-based feud would be a poetic way to close his career. Whether they do mask vs. mask as rumored (though the original plans to have the entire stadium break a record for wearing masks have been scrapped) or simply put Rey's career on the line, it will make for a very emotional finish. Sin Cara could easily be a surprise entrant, and have a dramatic showdown with his recent tag partner Mysterio. With their high-flying repertoire, look for a big elimination that could spark the final feud in an illustrious career.
