4) Brock Lesnar
The two have only met once at WrestleMania – two years ago – but that does not take away from the significance of how these two superstars just beat the hell out of each other in a three-match trilogy, which may have been the best feud of 2015.
An aging Undertaker rises once again to avenge the only loss at WrestleMania in 21 years.
You know, the one who defeated the one and was the one in 21-1, you get the picture. It also proved that a very suspect Undertaker, who looked out of shape and all but over with wrestling, got back off the mat and trained for these confrontations.
He looked every bit a challenger to Lesnar, who took the older veteran to Suplex City on more than one occasion. The arc and story told by these two men are like a few others, rivaling Rock-Austin and Triple H-Shawn Michaels.
