By the end of SummerSlam, we'll know who The Undertaker will take on at WrestleMania 29.
The answer is likely Brock Lesnar, and by the end of SummerSlam, we'll have gotten a good hint that all but confirms that is the direction things will go next April.
The Undertaker chooses his WrestleMania opponent. Top WWE officials can come up with ideas or suggestions, but it all must have The Phenom's seal of approval.
Lesnar makes the most sense, as it's the biggest draw. A feud with The Rock, while a big name on multiple platforms, wouldn't gain the momentum The Undertaker or The Rock's match should have for WrestleMania.
The Undertaker can build a match with a guy like Triple H or Shawn Michaels. They can say very little, or sometimes nothing at all, and the fight is sold.
The famous in-ring segment on Feb 21, 2011 where Triple H interrupted The Undertaker's return hits this point home. The two looked at each other and looked at the WrestleMania banner—it was on.
The Rock can't do this. He sells his tickets with his one-liners, songs, trash talk and all-around charisma. In relation to that, CM Punk and John Cena will be working in some triangle with The Rock on the road to WrestleMania.
Lesnar vs. The Undertaker is a phrase that sells itself.
Lesnar's name rings far and wide. The Undertaker is the name that the guy who hasn't watched in 10 years still remembers. The character has been so iconic and stands the test of time. Everybody who once had a family member or friend who watched wrestling remembers hearing or seeing The Undertaker.
Lesnar, the former champ of “real fighting," and the scary guy, The Undertaker. That's how it will be thought of by the causal fan—the fan WWE targets to buy WrestleMania. WWE knows the hardcore fans are going to buy it. It's WrestleMania. The company aims for new eyes to get drawn back in.
The history is there for the hardcore wrestling fans, casual wrestling fans and the UFC fans.
A staredown between The Undertaker and Lesnar after a UFC fight got the world talking and speculating if this was the start of a feud leading to a Lesnar return and a WrestleMania match.
At the time, who knows what it was? Perhaps it was real. Perhaps it was "let's do it, get people talking and see what happens in the future."
The future is here.
Lesnar has to go over Triple H. It won't hurt Triple H to lose the match, but it will hurt Lesnar if he loses. He needs a win to remind everyone why they should care about him. He also needs the win because we might not see him again until WrestleMania season.
Whether Lesnar wins by straight-up beating down Triple H or if Shawn Michaels plays a role, either way, Lesnar wins.
The beatdown continues after the match. Stephanie and/or Shawn need to be isolated. Handcuffed to something. Lesnar, with Paul Heyman screaming, destroying Triple H with nothing stopping them.
Would you be excited to see The Undertaker vs. Brock Lesnar at WrestleMania?
Then the gong hits. Lights out, lights on, The Undertaker in the ring. The staredown, then Lesnar backs off. Heyman has his jaw dropped with his eyes popping out of his head the whole time while he backpedals.
The Undertaker vs. Lesnar at WrestleMania seeds have been planted. Perhaps over time, Heyman speaks for his client "BROOOOOOCK LESNAR" and says he will not fight The Undertaker. He doesn't need to.
Perhaps The Undertaker eventually returns to television again around Survivor Series as rumored by F4WOnline.com (via WrestleZone.com) and holds Heyman hostage.
Regardless of the details in between, the end scenario is Brock Lesnar vs. The Undertaker at WrestleMania 29.
