yeah, even tho i'm not an ellsbury guy in terms of keepers i'd definitely take his long-term prospects over bourn's. and i'd take butler before all of them. billy has always hit for average and taken his walks and drove in a pretty good amount of runs, but last year he got to 29/107 which i hope is a paradigm upgrade for him entering the 30/100 calibur of hitter, which is the golden standard in fantasy baseball. like i said billy alwyas hits .280-300 and takes his walks, so if he's gonna keep on hitting 30/100 ish type power #s with his pre-established .280-300 thing then you definitely take that. billy's just outside of the big tier of "mashers" at first and if he busted out for a .315/37/115 type season you'd definitely wanna be there to have it. plus i think he's only ~25-27 so i think you could pencil him in for a good ~5 year run of prime career production, and i'd take that over the three principal guys mentioned in this thread.
so to rank it, in terms of keeping someone who you want to produce now with an eye towards the future, i'd rank them butler > ellsbury > bourn. short of thinking THIS IS THE YEAR and wanting to ensure that you've got ~40SB THIS YEAR then and only then would i go bourn... otherwise, even tho i've never been an ellsbury guy, he'd be my 2nd choice out of three cuz if he stays on the field nad gets back to what he's good at he could be a 15/50 type guy hearkening #s that remind you of carl crawford's walk year in 2010.
take a look @ my thread would ye?! phttp://www.fantasybaseballcafe.com/for ... p?t=456750
