#4 Kairi Sane
The main roster women's division hasn't seen a new face in a while, but there's every indication that's about to change. Kairi Sane appeared to wrap up her NXT commitments at Full Sail during last week's tapings and was backstage at SmackDown last week.
Added with Paige's comments, it seems a lock she's on her way to the blue brand.
Whether in singles or tag team action, she'll be a sight for sore eyes to a SmackDown women's division that has only had three credible top competitors for the past year.
#5 Drew McIntyre
Drew McIntyre should be a force to be reckoned with wherever he goes. If he stays on Raw, a major program for the Universal Championship will be in the works between him and Seth Rollins at some point. It's a real possibility he wins the title some time this year.
If he goes to SmackDown, however, the chances that he emerges as a world champion before the end of the year are even higher.
Keep your eye on McIntyre, because whatever show he winds up on, he should be a main event mainstay.
