Everyone loves an underdog - the ones that no one really expects anything of, who surpass those lowered expectations to suddenly achieve something great. Sports fans - and this includes wrestling fans, of course - love to be pleasantly surprised, and love to see the Little Engine That Could story play out on the pitch or in the ring. Its the feelgood hit everybody talks about for weeks afterwards. Underdogs give people something to believe in, even if its something as simple as the fact that the outcome of a match isnt always as youd expect. At their finest, the underdog can create the conditions for genuine emotional investment in their journey and their victory. But a quality underdog doesnt have to beat the odds to impress. They don't necessarily have to win - look at Rocky. They don't have to be the smallest person in the world, either: they don't even have to be the most loved. Its the effort that wins us over, the refusal to lie down and die. The payoff is a wonderful thing: but no underdog is ever a failure... if only they just keep getting up, keep trying, keep making us all believe. With that in mind, these are my picks for the scrappiest, most never-say-die underdogs in WWE history.
