#2 The Miz
It was a great 2017 for The Miz. I expect that momentum to carry over into 2018 when he should finally (and deservedly) get back into the world championship picture. A great start to 2018 would be a great showing in the Royal Rumble Match.
If the stars align, the Miz could enter early and then followed by his Miztourage and other allies such as Elias that can help protect him all throughout the match. Miz is a very smart wrestler. Take last year's Royal Rumble, for example, when he hung out on commentary until Brock Lesnar was thrown out.

There is a lot going for Miz as the Royal Rumble approaches, including being named Rolling Stone Magazine's Wrestler Of The Year. Those pieces could equal him being the one to last the longest in this year's match, and in my predictions I have him making it to the final three.
