#3 Aleister Black
Having mentioned him already, Aleister Black is another WWE Superstar who does not have a clear path towards WrestleMania after making his 'Mania debut last year. Black has had a stagnant year on RAW and SmackDown, getting a slightly slow push at the moment.
For a while, the former NXT Champion has been squashing local talent on RAW and only recently has he been involved in anything of note, aside from a tremendous series of matches with Murphy. Hopefully, his match against AJ Styles on tonight's RAW could speed up Black's possible 'Mania plans.
The Dutch Destroyer has been in line for a big push for a while now, but there doesn't seem to be any space on the WrestleMania card for him. The kickoff show battle royal is likely beneath Aleister Black's level and much like Ricochet, his biggest chance of getting on the card is a United States title match.
If the issue between Andrade and his Latino rivals is resolved before 'Mania, Black could very well step up to the challenge for the Show of Shows. But for now, he seems like a stepping stone for AJ Styles as he prepares to take on The Undertaker.
