#2 Ricochet
I'm torn on this one because much like Jake Roberts I would actually love to see Ricochet jump right to the WWE main roster and start checking names off of his list. But it doesn't seem like Ricochet would get the proper treatment if he debuted this year.
With so many stories going on toward WrestleMania and the main event seemingly already booked for the Universal Title with Lesnar vs Reigns, Ricochet's debut might be best served for NXT TakeOver: Philadelphia instead if he does appear in WWE.
Then again, AJ Styles came in at the #3 entrant during the 2016 Royal Rumble and although he didn't win he still had a great showing and went on to have an amazing first year with the company. But unless WWE plans on strapping a rocket to Ricochet's back (like he deserves) it might be a good idea for him to remain a spectator this year.
