#2 Lars Sullivan

We’ve already been informed that one of NXT’s biggest forces is coming to the main roster. The red brand will play host to the new monster on the block.
It is unclear whether Lars would enter the big league as a face or as a heel, but since Raw is now deprived of top-level faces after the departure of Roman Reigns and a possible injury to Braun Strowman, it can be assumed that he will come in as a face.

With Corbin, Lashley, Lesnar, McIntyre, and Ziggler playing the top level heels on the brand, along with Jinder Mahal in the middle, Lars would get a lot of good competition from the word go.
Even though Lars has not won any championships with the WWE in NXT, or hasn't any prior top level experience, he is still one of the most dominant wrestlers in the business who has only suffered one pinfall loss in NXT, and could be built parallel to Braun Strowman.
