It was perhaps one of the most controversial endings to a WWE pay-per-view in recent memory and it has left many WWE fans questioning who's idea it was to allow it to happen, but it seems it was all down to Vince McMahon.
The Undertaker tapped out to Brock Lesnar's Kimura Lock but no one actually saw it except the time keeper, who was on the same side of the referee.
It also makes no sense because the time keeper doesn't actually have the authority to over power the referee when it comes to in-ring decisions.

Vince's idea was to end the match in controversial circumstances because he wanted The Undertaker to finally get the win over Brock after 16 months, but at the same time he didn't want The Deadman to win clean because he thought that could harm the former WWE World Heavyweight Champion.
He preferred for Brock to pass out rather than tap out because he thought that would be a better plan than allowing Brock to be forced to submit for the first time. Instead it all turned out to be an ending that didn't live up to the hype of the match and in turn left the WWE Universe feeling rather disappointed.

WHAT COULD HAVE HAPPENED?
Paul Heyman was at ringside and WWE never thought to use him? Instead of using a timekeeper that has no attachment to the storyline at all, they could have used Heyman, he was on the same side that Undertaker tapped and he could have distracted the referee and allowed Undertaker to hit the low blow and in turn force Lesnar to pass out.
Much of SummerSlam, including the way the Seth Rollins vs John Cena title vs title match ended, looked like it was very bad storytelling on WWE's behalf.
Luckily it seems WWE made up for it on Monday night when they welcomed the returns of former nine-time tag team champions The Dudley Boys and WCW Legend Sting. They also unveiled a new member of the Wyatt Family and teased a future rivalry for John Cena.
But the weekend belonged to NXT once again. Triple H's show upstaged and out wrestled Vince McMahon's and whilst SummerSlam boasted the bigger matches, NXT delivered on all cylinders whilst many rate SummerSlam as the biggest letdown of the weekend.
Should Vince have let Undertaker win clean? Should Brock has actually been awarded the win? Do you think the ending made any sense? Use the comments section below to share your thoughts...
