Here's my crude (VERY crude) diagram, second base being on the left. I got an F in etch-a-sketch, good to see my skils are still at that level.
Is the study saying if both crude runners above begin moving at the same time, that the bottom runner has an advantage? Hmmm, I guess I'd have to see that to believe it.
I will concede that if the bottom runner starts moving before the top runner and times it so they are in roughly the same position at release, then they would have an advantage because they are moving.
From what I have observed watching games, so few runners are timing it anywhere close to properly, it's better to be closer than not. I suppose my bigger point would be base running is a skill that isn't emphasized enough and requires practice to get it right. At ALL levels. I expected to see better at the college level, I've been dissapointed.
