#5 Intercontinental Champion: Sheamus
WWE has two options for the fate of the Intercontinental Championship at WrestleMania 38. Sami Zayn is the Champion, although his win is yet to be televised. He is all but confirmed to face Johnny Knoxville at the event, but whether the title will be on the line is another question.
If it is, Knoxville might very well win the IC Title at The Show of Shows. However, cooler heads could yet prevail, and Zayn may end up losing it to somebody else before WrestleMania 38.
Out of everybody else on SmackDown, Sheamus is the best option to become Intercontinental Champion. He has received quite the push recently and needs the belt to complete his list of achievements in WWE.
#4 SmackDown Women's Champion: Ronda Rousey will defeat Charlotte Flair at WrestleMania 38
This seems pretty straightforward.
With the match already announced for WrestleMania 38, Ronda Rousey will likely defeat Charlotte Flair to win the SmackDown Women's Championship. It might even close Night One.
The Baddest Woman on the Planet could then go on to have a strong title reign, with matches against the likes of Naomi and Sasha Banks sounding exciting. But the real money match will happen at The Show of Shows next year, pitting Rousey against Becky Lynch.
