Duquesne vs Binghamton
 

R1 is keeping track of each setter's position by the placement of his feet. If the setter to his right is in the back row, his right foot is toward the back of the stand. When the setter is in the front row, the foot moved forward.

I've heard people talk about this, and I've even tried it myself, but I've never noticed it during a D1 match.

I'm not criticizing at all!! Please don't interpret this post that way. I just thought it was kind of funny to see it so clearly and say, "Hey, I do that!" :)
