#4 Enzo and Cass
Since WrestleMania 32, we have seen Luke Gallows, Karl Anderson, Enzo, Cass, Apollo Crews and Baron Corbin making a mark of their own on RAW. WWE usually injects talent on the roster on a gradual basis but this time around, the company has injected half a dozen guys at once and almost all of them are fan favourites.
Just observe the crowd reaction when Enzo and Cass made their debut on RAW! This is always good for the company as grooming talent for the future always pays and a step in that direction is always welcome by the fans. Given the dominance of The New Day on RAW, why not draft these two guys onto the SD roster? You already have some other tag teams to compete against the Champs on RAW and so such a move wouldn’t do any harm!
