#4 Keith Lee
At both Survivor Series and Royal Rumble, Keith Lee was able to prove why it's such a bad idea to sleep on him as a top-tier talent. This man is on a whole other level when it comes to possessing the sort of physicality you need to thrive in this business - and more specifically, in WWE.
At this moment in time, he has to be considered one of the leading contenders for Adam Cole's title, and when he eventually holds the belt, we think it's going to be a lengthy reign. When he does drop it, the right course of action would be to bump him up to RAW and SmackDown so that we can see him have wonderful feuds with the likes of Brock Lesnar, Braun Strowman, Roman Reigns, Drew McIntyre and more.
You need to be at your very best in order to beat someone like Keith Lee because if you aren't, he'll ensure that you live to regret the day you opened the door for him to burst through.
