Many on here have said how overrated or unproductive Jacoby Ellsbury is.
I'll use him for my question.
Ellsbury's OB% is at .354 (pretty good) but his slugging is a powerless .416 which results in a pedestrian .770 OBS....my question is how are his SB figured in and how is that computed?
This year he has 47 SB and only 4 CS....that is very significant....I know some of those followed a walk but could you not adjust his Slug % (not entirely accurately but a good idea of how much)...he has been thrown out 4x....so minus 4 total bases....but has moved up a base 47 times so add 47 to the total base total. Doing this takes his .416 and turns it into a .501 slugging....which pumps him up to a .855 OPS
I know one of the flaws is that off of some of his walks that the runners on 3rd never moved and a SB wouldn't be the same importance as the slug % I added because the runner didn't advance or score. Also if he had a runner on 1st or a slow one on 2nd and he singled, again adding a single and a SB or a BB and a SB takes away from the accurate measurement of the slugging % stat. Of course every player has some SB to add to it so for me to add his that way would have to also do everyone else's.
Anyways....what metric does this for me and a brief description of how it's figured. Pointing out flaws within it are welcome also.
