Dave Collins was fast. In 1979 he had these 3-35-.318-16 numbers. In 1980 he had these numbers 3-35-303-79. The last numbers 16 and 79 were stolen bases. I think that increase of 63 steals is the largest one season increase for a player who had played at least 120 games back to back. Here is a nice tight shot of Dave at Wrigley field.
