48. Juan Pierre (Rockies career WAR 4.1)
Pierre was the top-of-the-order catalyst in every lineup he graced. With all of that speed, he led the league in stolen bases three times and racked up 200 hits four times. However, he only produced an above average season per OPS+ twice. He was a pure speed player that was fun to watch run around, but produced only 18 total home runs in 14 big league seasons.
Despite the low power output, he always seemed to jolt every lineup he lead, the quintessential leadoff hitter from a bygone era.
