Number 5: Danny Richardson, (1884-1891), 15.8 WAR
Danny Richardson was the only member of the list that didn’t play past in the 20th century or later. Richardson’s first season was actually the franchises last season being known as the New York Gothams.
Richardson stole nearly 150 bases in his time with the Giants, and might actually have more. The stolen base didn’t have a box score place until 1887. Richardson was also a decent fielder. His offensive prowess was probably a smaller contributor to his career war than both his fielding and base-running.
