Here is a thread @ SOSH, regarding the Jacoby & SB.
Red Sox stolen base chronology - Sons of Sam Horn
I still remember I was so excited about getting Otis Nixon in 1994, thinking that hit speed (even though he was already like 35YO, and looked like 45YO)
I think Jacoby will easily pass Crisp, Lugo, and Nixon this year, if he is healthy.
