#2 Brock Lesnar felt Vince McMahon manipulated him
One of Brock Lesnar’s first major WWE moments came at SummerSlam 2002 when he defeated Dwayne “The Rock” Johnson to win the Undisputed Championship.
The only other one-on-one match between the two men took place at a live event in The Rock’s hometown of Miami in March 2003. The Rock made sporadic WWE appearances at the time, while Lesnar was two weeks away from facing Kurt Angle at WrestleMania 19.
Lesnar said he had no problem losing to The Rock in Miami, especially as his opponent agreed to lose to him seven months earlier. Still, he did not like the fact that he was unaware of the finish until the show had already started.
In his book, Lesnar speculated that Vince McMahon did not want The Rock or WWE agent Jack Lanza to inform him about the outcome. That way, by the time Lesnar found out, it would have been too late for him to try to change the finish.
“Just from the look on Dwayne’s face and the tone in Jack’s voice, I knew they were in on something I wasn’t. It was obvious to me that Vince, Dwayne and Jack were all in cahoots, and I wasn’t being smartened up to the situation until the very last minute. That night changed my attitude toward the WWE, because it’s when I started to feel Vince was a manipulating b*****d, and that I was being played,” Lesnar said. [H/T talkSPORT]
Despite the live event incident, Brock Lesnar and The Rock have always been on good terms. The Great One disclosed on Twitter in 2013 that he was originally supposed to return to the ring at WrestleMania 30 to face Lesnar. But due to The Rock’s schedule heading into the show, the match did not happen. Instead, Lesnar defeated The Undertaker and ended The Phenom's undefeated streak at WrestleMania.
