#3. Stone Cold Steve Austin has never defended the WWE Championship at WrestleMania
When it comes to who the biggest stars in WWE history are, there's no doubt that Stone Cold Steve Austin sits near the top. There's an argument to be made that he was the biggest draw ever, though a certain other Hall of Famer might slightly disagree with that.
Be that as it may, Austin was also one of the most popular WWE Champions of all time. Part of that had to do with the thrill of watching him overcome all the obstacles that Vince McMahon and his cronies put in front of him.
In short, Austin was at his best when chasing the title. As a result, he competed in each of his championship matches at WrestleMania as the challenger.
WrestleMania XIV saw Austin earn his first victory against Shawn Michaels. The next year, he regained the title in the main event against The Rock. Finally, at WrestleMania X-7, he once again defeated the Great One, albeit as part of an ill-advised heel turn.
The Texas Rattlesnake may have been one of the greatest world champions of all time, but he never once walked into WWE's biggest show with the title around his waist. He did, however, usually walk out wearing it.
