Does Nakamura need to expand his moveset?

Not a troll post (promise), I'm genuinely curious about your opinions. I remember listening to the TIJ podcast he was on and he said something to effect of "It's not the moves that matter, it's what you're doing between the moves." Do you feel this is accurate? Can he get (or stay, depending on how you gauge current fan reaction) over with the average RAW / Smackdown crowd doing nothing but knee strikes, an exploder suplex, and a body slam sprinkled in there occasionally?

I make this post fully aware that the current Universal Champion does nothing but a German suplex and the chosen one isn't much more than a Superman punch and a spear.
