6. Big Cass
Big Cass is the modern day giant in the WWE with just one active competition named Big Show (will be covered in next section). Cass had recently imploded his relation with Enzo Amore and is currently working on his singles career, he defeated Enzo at the inaugural Great Balls of Fire pay-per-view.
Big Cass is also 7 feet tall and while many tall superstars aside Kane and Big Show haven’t enjoyed a healthy run at the top, Cass might strike the gold given if the WWE officials choose to invest in him.
