Many of Cena’s biggest rivals have been central to his rise, Cody Rhodes, CM Punk, Randy Orton. Even when tensions ran high, there have been moments of respect, like teaming with Punk to fend off Seth Rollins and The Vision.
Given Lesnar’s history of dominating Cena, a win here would be significant. Cena could extend his hand afterward, and Lesnar might reluctantly accept, marking the end of their rivalry if this is indeed their final meeting.
