4. Bray Wyatt vs. The Undertaker
The Undertaker's appearance at this year's Wrestlemania, if it even happens at all, is likely to be a strange one. This is the first time for a long time that 'Taker would just be taking part in a regular match at the annual showpiece - the ending of the much-vaunted streak is still a headache for many, and a lot of fans are finding it difficult to see how 'Taker fits into this year's proceedings. Bray Wyatt draws a lot of supernatural comparisons with The Undertaker, and is almost a more-human version of 'The Phenom'. Wyatt no longer has Rowan & Harper at his side, meaning this could be one hell of an interesting tale of mind games between the icon and the younger model. There's an argument to be made that it might not mean as much, but a win over The Undertaker, or even a strong performance, at Wrestlemania would go a long way to cementing Wyatt as a fixture at the top of WWE cards for years to come.
