#2 Disregard for authority
Destroying the Authority and its minions (J&J Security) to get to Seth Rollins after he cost Lesnar the main event and the WWE Title at WrestleMania 31, was something that the WWE Universe thoroughly enjoyed.
Albeit, that was more due to the fact that they were tiring of the incessent power-laundering and underhanded ways that had earmarked the Authority.
Beneath the surface though, the undercurrent of disregard for the powers-that-be that was displayed by Lesnar went quietly unnoticed. There have been momentary glimpses of it since, like when he single-handedly dismantled J&J Security’s car, or took out his fustration on an innocent and hapless Michael Cole. .
But never was it in full display as when he unnecessarily laid out Shane McMahon with an F5 to close out SummerSlam, just as the SmackDown commissioner ran to the ring to ensure the safety of a profusely bleeding Randy Orton.
