The inclusion of Floyd Money Mayweather at Wrestlemania brought a whole load of non-wrestling fans' eyes to the WWE product. Mayweather is seen by many to be the greatest boxer on the planet and often suggested as the best pound-for-pound boxer to have ever lived. If an appearance from him at Wrestlemania wasnt enough, the intrigue was only heightened by having him compete in a match. The coming together of two physical industries, in this case boxing and professional wrestling, always brings with it a huge crossover appeal. To make this even more of an attraction, the 58undefeated Mayweather was given the 7, 425 lb Big Show as a mismatched opponent. We all knew that Mayweather was going to be the victor, but that didnt stop us all tuning in to see this modern David vs Goliath match-up for ourselves. Money Mayweather claims to have received a $20 million payday for his work with the WWE, and his presence certainly brought a massive amount of global attention to Vince McMahons product.
