If we can get a LSM the quality of Cena vs Umaga (RIP) at Royal Rumble '07 then I will be happy.... another cool fact.. the 2 losses in LSMs from Cena both came in matches in which there was outside interference. I think we can all agree there is a 100% chance of outside interference in the Wyatt vs Cena LSM.
The only one that I would call "clean" would be the Umaga one, hell you can argue that Ryback won clean since he hit the power move and got to his feet first.
Still, there's a difference between a dirty finish and bullshit, you can have a satisfying dirty finish. The 2 losses both were within the rules - especially the Edge loss, with the amazing spotlight spot - so I didn't see much of a problem with them despite the interference. The only BS one was the duct tape.
You have a better chance of getting a title shot than Titus.
