5. Daniel Bryan
Nobody is more over in the WWE at the moment than Daniel Bryan. As people like Sheamus and John Cena rest up from injury for possibly the rest of 2013, the company is now trusting Bryan to be the alpha-babyface of the company. Somewhere down the line, Bryan will get a real, deserved championship run and it could well happen at Wrestlemania 30 if the WWE want to string the angle with the McMahons out that far. However, as far as babyfaces go, I don't think there is another superstar who could defeat the Undertaker at Wrestlemania 30 and still get away with it without a heel turn (with the possible exception of CM Punk). For that reason alone he has to be a viable option for the Streak Match. There is little doubt that the match would be fresh in everyone's mind- for the two have never faced off in singles competition and Undertaker has sung the praises of Bryan as a performer, so the idea of a lack of respect needn't be thought of. Furthermore, if the WWE are truly hooked on the idea of Bryan as the next big star, then the idea of snapping the Streak may be the final push he needs. However, it seems at the moment that Bryan could well be busy with other commitments at Wrestlemania. I wouldn't be surprised if they allow him to be shunted around for the rest of 2013 without tasting gold again until he wins the Rumble in 2014. Having said that, if they decide to pull the trigger on him earlier (say, Survivor Series like they did with Punk in 2011), then maybe, just maybe the Beard and the Phenom could close out the show with the gold on the line. Like I said, it's an outside chance.
