I understood what you were saying but what I meant was how many more runs would Bourn produce due to his speed as opposed to the other options available? In order to use his speed, he has to get on base and juding by his career stats a .350 OBP is about what you could reasonably expect. ASs for the second part, in the short term they *may* have Jackson as that guy. If not, perhaps probably not, the comparison would be Bourne vs Dejesus. In which case Bourne's value lies more in his defense than his ability to score more runs because he is fast. To put it another way, I'd rather take my chances that DeJesus can provide what Bourne does offensively in the short run and hope that one of Jackson, Soler, Almora, etc pan out within 5 years.
