I guess the question is, is it stupid for guys like Duran and EDLC when they succeed at it most of the time? Maybe if Vladdy had 90th percentile speed his absolutely horrendous baserunning mistakes would work a lot more often and we would think of him as an exciting runner. But then the flip side is someone like Teoscar Hernandez, consistently around the ~85th percentile in sprint speed his whole career, but sitting at a -1 in value added on the bases his entire career. Randy Arozarena is another example, in a more extreme version of a guy who is aggressive all the time but it's never worth the risk he puts himself into. You want guys like that to be aggressive, steal extra bases with their speed, as long as they have the IQ and instincts to prove it worthwhile. If it was as simple as speed covering up your deficiencies, Teoscar and Randy would be providing lots of baserunning value. Duran and ELDC combine speed, hustle, and just enough risk that it pays off for them to make "bad" baserunning decisions for most players.
