It's all well and good that you think Kane will win, but I think you may be exaggerating just a tid when it comes to the Big Red Machine. For a majority of Kane's career, he has been a midcarder. Just face it. Other than his first year and 2010, a cup of coffee with the likes of HHH and Benoit, Kane's been pretty much in the midcard.
I applaud your efforts on giving Regal his due but there is no way in any universe that Regal can out-muscle, out-pop, or out-do Kane. There are too many factors in Kane's favor here:
1. Regal has sustained many injuries in his career which would make him weaker to Kane who has been known to be one of the healthiest and most consistent upper-midcard -> main-eventers in the business.
2. Kane is more powerful.
3. Kane pairs that power with his uncanny agility.
4. His overall popularity stretches far beyond one country and his super stardom dwarfs Regal's.
5. Kane was world champion in two different eras and generations for a reason; he was THAT dominant at those particular periods.
6. Kane is sadistic enough that Regal's use of brass knuckles wouldn't be enough to keep him down.
7. Davi's point about Kane's mask is something I never thought of but definitely cannot deny in this bout.
8. Didn't Regal fall asleep in a PPV match against Kane once? Don't you think that would be detrimental towards Regal gaining a victory here? He has chronic insomnia... the guy is susceptible to just about ALL of Kane's attacks.
9. How about this:
Kane was DESTROYING Regal until outside interference happened.
EDIT: Here are some more facts that will cover more angles of arguments made on Regal's behalf:
9. Kane is more popular than Regal as a babyface AND as a heel.
10. Kane has sold more merchandise than Regal.
11. Kane is feared by more wrestlers than they are by William Regal.
Guys, you can sugar-coat it all you want but Regal doesn't stand a chance.
