#1 Seth Rollins - WrestleMania 31
At WrestleMania 30, Brock Lesnar ended The Undertaker's legendary streak. Months later, he squashed John Cena at SummerSlam 2014. The WWE Universe was clamoring for someone to step up to Lesnar and end his reign of terror.
WWE chose Reigns to be the one to put Lesnar down, but it led to fans turning on Reigns and his victory at the Royal Rumble 2015 PPV was met with loud boos from the fans, despite The Rock being by his side.
