5 reasons why Vince McMahon won't let Becky Lynch and Seth Rollins lose their titles at Extreme Rules 

#3 & #2 Seth Rollins will lose against Brock Lesnar and Becky Lynch will lose her title to Ronda Rousey

Is it the plan?

Brock Lesnar wants to take his revenge from Seth Rollins, as he beat him at WrestleMania 35. On the other hand, Ronda Rousey is currently injured but once she returns, WWE would (most probably) want to continue her feud with Lynch.

Lesnar has the Money in the Bank briefcase and it’s almost confirmed that he would successfully cash in his contract against Rollins when the time comes, and it may happen during SummerSlam or the Royal Rumble.

And according to rumors, Ronda could return to WWE soon, but it wouldn't happen before October. If these two Superstars are going to defeat Rollins and Lynch then there’s no way Baron Corbin and Lacey Evans would win titles at Extreme Rules.
