43. Jerry Dipoto (Rockies career WAR 5.8)
Most people today can only associate Dipoto with the photo above. What many forget is he was a fairly successful relief pitcher for eight big league seasons, four of which were spend in the Mile High City.
He was above average to All-Star level all but two years of his workman-like career. He never had less than a 110 ERA+ as a Rockie, culminating in his best year of 1998 where he had 19 saves, pitched 71.1 innings, and accumulated a 1.8 WAR.
