#5 Ronda Rousey vs. Sasha Banks
Ronda Rousey and Sasha Banks should be able to keep things exciting in the fifth spot on the Rumble card. Placing the match here also opens the possibility of Sasha Banks entering the women's Royal Rumble match, since she's unlikely to win the title.
When you think of Banks' performance at last year's Rumble, where she lasted nearly an hour and made everyone she came in contact with look good, she should be part of that match. It would also be a good way to tease coming feuds in the tag team division.
#6 Men's Royal Rumble match
With three firecrackers in a row, it would be best to give the crowd some time to recharge its batteries. Rumble matches can do that, as the pace slows at times while picking up at other times.
Like last year, the big story is centering around the women's Royal Rumble match, so the men's match should take place before it. That's just the way it's worked out.
Regardless, a Rumble match is still a Rumble match. The guys will put on a show, slowing down or picking up the pace as needed, until we hopefully get to the right winner.
