While the PPV itself was praised, the two World Title matches was a bit too short.When looking at each match, it's not hard to see why WWE made the decision to make them short. Goldberg vs Braun Strowman was never going to be a long-drawn-out match, while the clash between Drew McIntyre and Brock Lesnar was likely better off being a short and explosive one.While fans may logically have wanted to see both McIntyre and Lashley main event WrestleMania this year, the company may have wanted the most explosive match on the card to start Night 1.If you aren’t main eventing, open the show. Can’t wait to hear the @WWEUniverse live cheering and in person.........and then hear absolute silence when I take down your “warrior”. 24 hours...⌚️#AlmightyEra #WrestleMania https://t.co/Hpi843cBKR— Bobby Lashley (@fightbobby) April 10, 2021While WrestleMania 36 with a coronation for Drew McIntyre, this year, we could see it happen once again at the beginning of the show. Bobby Lashley didn't seem to have an issue with opening the show, and he will get to be the first of two men to see the live crowd on the main card.It was over four years ago at No Mercy when WWE decided to use the World Championship Triple Threat Match (between AJ Styles, John Cena, and Dean Ambrose/Jon Moxley) to open the PPV rather than close it.That was due to the National Election Debate, and while this is different, it isn't a bad choice to open the show at WrestleMania.
