He's never able to win the big games — this is how many critics in the NFL media and within the outside fan arena view Sam Darnold. Granted, Darnold hadn't played in any "big" games until he landed with the Minnesota Vikings last year, so his big game resume isn't lengthy.
Still, last year, he had big games, and he was unable to win the one that mattered most, which eventually landed him with the Seattle Seahawks. Upon his arrival, he was expected to win big games for them; that was the reason GM John Schnider went with Darnold over Geno Smith.
