Welpe wroteThe NCAA didn't completely change it did they? I was under the impression that about to receive was still a valid exemption from obstruction but that a fielder couldn't completely block a bag off on a pick off play.
Actually, they did completely change a few years ago, but then modified the change last year to allow for "about to receive" on thrown balls except for pick-off plays, as you stated. I should have clarified that. 🙁
