#3 Goldberg would not have won at Wrestlemania XX
Brock Lesnar's final match in WWE for eight years came at Wrestlemania XX on March 14, 2004 versus former WCW Champion, Goldberg.
The original booking plans had Lesnar defeating Goldberg clean. However, plans changed when Lesnar gave his notice to WWE five days prior to the show.

WWE felt there was a greater chance of Goldberg re-signing for the company post-Wrestlemania than Lesnar, which is why they changed the result.
A win for Lesnar over a legendary name like Goldberg at WWE's biggest ever event would have further enhanced his young career that already featured three WWE Championship reigns and a King of the Ring and Royal Rumble victory to his name.
A Lesnar win here would have meant that WWE would have needed to find another selling point for their Survivor Series 2016 match-up between Lesnar and the returning Goldberg. Built around the fact that the unbeatable Lesnar had never defeated Goldberg led to huge interest in the WCW veteran's 2016-17 comeback.
This would have held nowhere near the same appeal if Goldberg had lost at Wrestlemania XX. In fact, it may have meant that the Goldberg return would not have occurred at all.
