Guys I am having an argument with my friend Paul Sporer (from Fangraphs) on twitter about speed. So I have a question for guys like wupk, nsacpi and Enscheff: How much can you infer about a player's speed based off of one single event? Can we infer that Acuna has elite grade speed based off of last night's time of 30.3 ft/sec or is it too small of a sample to learn anything? I was arguing that speed is a more repeatable skill than something like power or hit tool, so if Acuna can run 30.3 ft/sec then that puts him pretty close to the top of the league in sprint speed. He is arguing that we basically learned nothing from that event. I admittedly know very little about speed and how it should be graded and how much sample matters so I could be wrong. Paul is a very smart baseball guy.
