3. The Undertaker vs. Brock Lesnar (Rivalry Of The Year)
Initially, it seemed like The Undertaker and Brock Lesnar would face off again at WrestleMania 32. That plan was abolished in favour of having the infamous pair match up at SummerSlam and Hell In A Cell. The latter bout seemed to be a closing point in their feud, taking the place of any prospective 'Mania battle. If this was to be the last time Lesnar and 'Taker faced one another, it was epic. That can be the only choice for 'Rivalry Of The Year' in the 2015 Slammy Awards. WWE may wish to throw a curve ball of sorts for this one, but the other nominees are a bit more limited. For example, whilst Undertaker vs. Brock felt huge, Seth Rollins vs. Randy Orton was a passive feud for the former. Team PCB vs. Team Bella vs. Team B.A.D didn't last that long either. Other picks fans can vote for are John Cena vs. Rusev and Bray Wyatt vs. Roman Reigns. Both had their positives, but the winner must surely be The Undertaker vs. Brock Lesnar. Reigns and Wyatt deserve plaudits for their own Hell In A Cell match this past October, but it couldn't top the true main event.
