Yes FP, good description.
I was a little surprised that EricF thought the bat was dragged AFTER the point in the swing that he posted. The dragging, in a sense, had already taken place. That's why the hitter ended up in the orientation that EricF posted.
I saw the pic as being an example of a hitter in the process of dragging the bat. I did not intend to indicate that this position was where bat drag started. To me, bat drag clearly started earlier in the swing.
I have removed my original description to hopefully eliminate confusion for future readers.
It would be helpful if you could post a couple of pics of bat drag earlier in the process so people can know what to look for while working with their hitters.
