#2 Sami Zayn
The Underdog from the Underground was playing the role of a heel before he suffered an injury which led to him being on the sidelines.
Zayn could return as a babyface, as he could talk about how Lashley was the reason why he was on the sidelines for so long.

It could create a solid storyline in which the fans could get behind Zayn again, as The Underdog is yet to hold a title on the main roster.
But due to Zayn being a babyface for the majority of his career, he wouldn't have a problem in getting the fans back on his side.
There is no doubt that the WWE Universe would begin to root for Zayn again, and seeing The Underdog defeat Lashley for the title could be the epitome of David conquering Goliath.
