#4 Lio Rush
Lio Rush has had a very interesting career in the WWE so far, and unfortunately, not all of it has been positive, and after his latest episode of heat backstage, it looks like WWE may be repackaging him and sending him back to NXT.
In the ring and on promos, Rush has all the talent in the world, but for some reason, he sees himself as much bigger than he is, and it's constantly hurting him, so a trip back to NXT could even humble him and help his future in the company.
Right now, like Sasha Banks and others, we have no idea what's happening with The Man of the Hour, but his in-ring work translates perfectly with NXT, and it could churn out some incredible bouts.
When he arrived in WWE, Rush was seen as main roster ready very early, and skipped through NXT, but a run down there to show him how things are done properly in WWE is essential, and may be on the way very, very soon.
