Ryback's clothesline is awesome. It's like Goldberg's spear, as well as his finisher being like the jackhammer. Yes, I know, the moves are not similar at all, it's just that him using a running move than a lift up finisher while squashing people reminds me of Goldberg. (What's the technical name of his finisher again? Fisherman suplex lift into a running back drop or something?)
Lesnar putting him over as a monster would be great.
