Denard Span
.392 OBP, .807 OPS, 69.6% steal success, 23 SB's
Jacoby Ellsbury
.355 OBP, .770 OPS, 85% steal success, 70 SB's
The reason I'm asking is I'd like to get the feeling of the board on the importance of "conventional" leadoff attributes, such as a high level of speed, versus the more modern values a guy like Span brings with his substantially higher OBP.
The reason I bring up those two rather than more archetypal examples that isolate specific attributes like, say, Carlos Gomez vs. David Dejesus, is that I'd like to see how people compare two players who use their skillset effectively, and which attributes are preferred when both players are doing their job well. I wanted to compare players who were very good at what they did, and find which parts of the skillset people considered most important.
These might not be the best examples in the history of ever, especially given Jacoby's adequate OBP, but I felt Span's low success rate sort of makes up for that, at least enough to allow people to kick off a conversation about it.
