Obstruction? (photos: high bandwidth only!)

[CecilOne]

I remember that play and thinking:
- whether the runner changed approach before on camera (i.e., impeded or not)
- where the ball was when the runner changed approach (i.e., did about to receive apply?)
- runner reached plate before ball arrived (frame 3, safe either way)
- anywhere but NCAA, OBS
- whether to consider INT if another runner played on
- wishing I could see the whole play

As I do not like resorting to HTBT, my TV perception was the ball is too late to be ABTR and the runner only slid to avoid the block, so OBS.
