Short answer: Vanilla Midgits.
Long answer:
Nash and Bryan are very similar figures in terms of their wasted opportunities, spouting complete bullshit they 100% believe that sounds like they're fucking with you, never actually being real draws, etc.
They're both guys who should have been over forever, Nash for his fucking size and Bryan for his exceptional wrestling. Both were limited to being extremely over for one small period of time before being overshadowed. Both fuck everything up by making goofy goober faces at the worst possible times. Both are a testament to how much charisma and promos matter in wrestling, and how being perfect at size or perfect at working matches can get you to the finish line, but you'll never come in first place. Nash was always below Michaels, a midgit, despite looking way more like a main event guy. Bryan was always below big guys on the card. Even Sheamus at one point, because he can't even promo as well as Sheamus. Hell, both are two guys that can't out promo Sheamus, and the only reason they're more important than a guy like Sheamus is the 1 small corner of wrestling they are the best at, size for Nash, mat wrestling for Bryan.
tl;dr One is big, one is small, both are top of the midcard/bottom of the main event guys that could NEVER draw as top guy.
