At this point, whether someone is over or not doesn't matter.
Mainly because a name star ending it will be more believable than a non name star, or some one who still needs the rub, coming in and ending it.
For instance.
Triple H, Ric Flair, Shawn Michaels, CM Punk, Mark Henry, Kevin Nash, and a host of other big superstars couldn't end it....... but a Seth Rollins, or Roman Reigns, or a Sheamus can?
Doesn't work.
And that's not take away from them, or even those who have tried and lost. But lets get real....... It took Triple H three tries, and Shawn Michaels two, to even come close.
Having some fresh face come in and end it first time out, perhaps dominantly, would just be wrong at this point.
Maybe 10 years ago, when the Streak wasn't so big (like they almost did with Orton), but its too big for that now.
