Brock Lesnar left WWE in March 2004, after losing a match to Bill Goldberg at WrestleMania XX, to try to pursue a career in mixed martial arts. In April 2012 he returned to Stamford after an eight-year absence, performing primarily as a part-timer.
On April 6, 2014, at WrestleMania XXX, The Undertaker's 23-year unbeaten streak at WrestleMania ended, while between 2017 and 2018 he held the Universal Championship for a record reign of 503 days (April 2, 2017 to August 19, 2018), which is the longest in the history of the title.
During an interview with Sportskeeda, Chris Jericho revealed that he isn’t on board with the notion that Brock Lesnar is now a free agent.
Y2J on Brock Lesnar
“The only reason why the rumor’s there is somebody said ‘free agent’.
I don’t think he’s really a free agent at all. I think it would take so much money to pry him away from Vince McMahon on Brock’s end and then for Vince to approve that… I mean, Vince has two billion dollars in the bank.
What are you going to spend on Brock Lesnar that Vince isn’t going to match? And Vince and Brock have a strange love affair, to begin with" - Chris Jericho said. On if Brock Lesnar would leave WWE, he added: “So would Brock fit in at AEW? Would he pay back his salary that you would pay him to be in AEW? Who’s to say, but I think UFC, AEW… I think it’s just another one of the dances that Vince and Brock like to have where Brock’s contract expires.
Vince lets it expire, and then they stay away from each other until the next Saudi Arabia show or the next show that has people in the crowd, or WrestleMania, whatever it may be. So I don’t think Brock is really a free agent in the sense of the word, I just think he’s like currently not under contract right now.
The amount of money it would take him to tear him away from from the world of WWE would, A, be astronomical, B, Vince will never allow it to happen and, C, I don’t know if you could make that investment back, or if it would even be worth it for AEW at this point in time or UFC, or any company other than WWE”.
Y2J also talked about the company: “I’m very happy in AEW. I’m very creatively stimulated here and I enjoy coming to work every time, every week, every month, whenever it may be, and to me, the fact I’m having as much fun as I’m having and doing the work that I’m doing now after almost 30 years in the business is a testament to the longevity that I have and also to the great environment that AEW is providing for me”.
