3. The Undertaker Wrestles As A Heel
When The Undertaker returned at Battleground to finally get his revenge on Brock Lesnar for conquering The Streak at WrestleMania XXX, an interesting thing happened: he delivered a low blow. That's wildly out-of-character for the Deadman of recent years, and it appeared to be an indication that he had returned as a heel. However, the WWE clearly hadn't foreseen the hugely positive response he would receive that night and any plans to turn The Undertaker heel appeared to have been dropped by the time he was brawling with Lesnar the next night on Raw. Another low blow to The Beast on this week's episode (where Brock was very much the home town favourite) seemed to finally make it clear that The Undertaker is the heel in this feud, and it's a safe bet to assume that that is how he'll wrestle their match at SummerSlam. How the Brooklyn crowd will respond to this is hard to say, and it could be that they'll be split between these two heated rivals. That's just going to help add to the excitement and big fight feel though, and a heel Undertaker - which we haven't seen in a very long time, similar to a babyface Brock Lesnar - is going to ensure that this match plays out in a very different way to their last encounter.
