The two biggest matches of this year's card are, of course, Reigns vs. Triple H and Undertaker vs. Shane - but WrestleMania 32 is really lacking a huge clash of titans type contest. WWE may have bitten off more than they can chew with their recent trend of shoving big stars in dream matches. The past few years have given us Triple H vs. Sting, Lesnar vs. Undertaker and Cena vs. Rock (twice). This year there's certainly a gulf on the card. Unless somebody steps into the Hell in a Cell match in Shane's stead, we're probably looking at the first 'Mania without a big box-office encounter in four or five years.
