#3 Kurt Angle's final opponent
There may be a reason why WWE has chosen Baron Corbin to be Kurt Angle's final opponent ever. This is because he may be a decoy, who'll garner heat as he walks to the ring, only to be replaced by The Undertaker.
While most fans want John Cena to take Baron Corbin out, I daresay they wouldn't be too displeased if The Undertaker takes his place as well. The Undertaker and Kurt Angle have fought some great battles through the course of history.
Or maybe Baron Corbin wins the match and decides to be merciless when the Olympic Gold Medalist lies prone on the mat. The Undertaker could certainly interrupt the proceedings and take Corbin out, to the delight of the crowd in attendance.
I'm guessing that everyone in the arena will have chills down their spine when the gong sounds, none more so than Corbin!
