#3 Mustafa Ali

Mustafa Ali was promoted from 205 Live to SmackDown last year. He instantly got into a mini-feud against Daniel Bryan and is currently in a feud with Samoa Joe.
He took to his new role like a fish to water and is a very popular member of the SmackDown roster. The fans like him and management seem to be behind him as well.

An iron man performance will be the perfect tool to make him more popular among the fans. Given Ali's independent background and amazing in-ring ability, he will be more than fit enough to fulfill the role.
His inexperience might be an issue, but it is nothing that cannot be resolved. If WWE wants to cement Ali's role as a babyface, a long hard fought stint in the Rumble match followed by elimination by a hated heel will be perfect to put him over with the entire crowd.
Ali's high flying antics can also keep the Rumble match exciting throughout. He can even start the match and go all the way.
