#3 Brock Lesnar should end his career in WWE
Now that Brock Lesnar is not under contract with WWE, he could jump ship to AEW or return to the UFC. The second option is improbable because Lesnar officially retired from MMA for the second time in 2017. Chances may be paper-thin, but Lesnar could return from retirement. The Beast is also unlikely to join AEW as there has been little discussion of Brock Lesnar joining the AEW roster.
A cloud of uncertainty surrounds Lesnar at the moment. However, the Beast should return to WWE, and that is the most likely scenario. The timing remains unclear, but Vince McMahon wants Lesnar to compete in front of live crowds. If that is the case, then the former Universal Champion may return sooner rather than later. His return would be best for business.
The Beast Incarnate should end his legendary career in a WWE ring. Before becoming a major player in the UFC, Lesnar made a name for himself in WWE. His meteoric rise to the pinnacle of WWE was rapid. If it weren't for his initial WWE singles run that launched him into the stratosphere, Lesnar would not have become the huge star he is today.
A final singles run in WWE before riding off into the sunset would be a great dose of nostalgia. It would also be very comforting to witness Lesnar end his career on his terms. His career started in WWE, and it is logical for it to end in WWE too.
