#3 Jinder Mahal

Jinder Mahal has been sidelined since last year after winning and losing the 24/7 Championship. It has been speculated that Mahal has been cleared for action and should be ready to return to the ring at any point. The former WWE Champion could return and is flexible enough to fit in a few different spots.
He could return as someone to help the babyface run for Drew McIntyre and provide a big win for the Rumble winner on his way to Brock Lesnar. The two have history and Mahal had success in WWE before McIntyre has and that could provide a great story for the two.
Cody Rhodes' uncle is a WWE Hall of Famer. More details HERE.
Also, he could be a return for the Andre The Giant Memorial Battle Royal in which he could win the match that he almost won years ago. However, if they decide to bring him back they should capitalize on his prior success as World Champion and the fact that he has been on the shelf for a while because his presentation is top-notch.
