#5. Brock has dominated wrestling legends.
When you talk about great wrestling champions, you have to talk about the men they faced over the course of their career.
"Nature Boy" Ric Flair is considered a legend, not just because of his many title reigns, but because of the legendary wrestlers he's defeated along the way. Men like the "American Dream" Dusty Rhodes, Harley Race, Ricky "The Dragon" Steamboat and Macho Man Randy Savage all fell before Ric Flair.

Likewise, all of Brock's contemporaries have fallen before his might, and often in dominating fashion. The Undertaker, John Cena, The Rock, and many others have tasted defeat at the hands of Brock Lesnar.
When you defeat legends, you become more legendary yourself. Brock's handling of a veritable who's who of modern wrestling greats is another reason why he's the greatest WWE champion of all time.
