#1 The Beast vs The Big Dog

Our long national nightmare is over. Roman Reigns will face Brock Lesnar for the Universal Championship at WrestleMania 34. Job well done, if only it were that easy.
Reigns won the Elimination Chamber and boos rained down. Brock Lesnar is expected to leave the company post-WrestleMania 34. This could very well be a Golderg vs Lesnar from 15 years back and it is the last thing WWE would want.
WWE should absolutely resist the temptation of making alterations to this match and adding another competitor. Reigns and Lesnar are the two Alpha-Males of the company, their match will be a Slobber knocker and is deserving of headlining WrestleMania.
As far as the boos are concerned, have Paul Heyman turn on Brock Lesnar.
Did a WWE Hall of Famer predict John Cena's heelish ways long ago? More details HERE.
