10 Biggest WWE Superstars Never To Headline WrestleMania

3. Eddie Guerrero

One of the purest, smoothest in-ring workers wrestling has ever seen, there's no doubt that Guerrero's passing was a heartbreakingly tragic one. He proved to his many doubters that a man his size could hang with the big boys, rising to the top and capturing the hearts of WWE fans around the world. Although afforded a 'Mania moment following Chris Benoit's title win in 2004, his own match was further down the card - and the moment has since understandably been tainted. Equally capable of playing a devious heel and a brave babyface, Eddie's revered legacy would have been even further cemented by a big WrestleMania main event of his own. Most Likely Opponent: Brock Lesnar. Guerrero's sneaky heel shtick was fine for the midcard, but he rose to true superstardom as a plucky babyface. His bloody win over JBL at the Great American Bash has gone down in folklore, but he was at his determined best facing off with the Next Big Thing.
