The Dead Man has returned! The Undertaker made his return to WWE at Battleground, attacking Brock Lesnar during The Beast's WWE Title match with Seth Rollins. This was 'Taker's first appearance since WrestleMania 31, where he defeated Bray Wyatt in his first match since he fell to Lesnar at WrestleMania XXX. Despite rumours circulating online that The Undertaker could and most likely would be making his return at the show, the fans still reacted with surprise at his appearance with the St. Louis faithful going wild at the sight of The Phenom, who cost Lesnar the WWE Title and dropped him with a chokeslam and two Tombstone piledrivers. It was a bold statement, one that has no doubt left fans actually wanting to tune into Raw tonight to see what happens next. But despite the buzz coming out of Battleground, is a Brock Lesnar versus Undertaker match really the way to go? It appears as though WWE have scheduled the match for SummerSlam, but they may have made a giant misstep in their haste. At one point a dream match, Lesnar versus Undertaker in 2015 is problematic for a number of reasons. Are WWE doing Brock, 'Taker the fans and themselves a disservice by booking this clash of the titans at SummerSlam?
