Would you call obstruction?

[Steve M]

Tom has some good point, as usual. For this post, the one I most appreciate is:
"As I said above and previously several times, just because a fielder is blocking a base or standing in the base line without the ball does not make that fielder guilty of obstruction. Impeding the runner makes that fielder guilty of obstruction. Don't make the call unless the runner is actually impeded."

At the NCAA clinic, one major point was to change the priority of how we look at the play. Look for obstruction.
According to the presentations, we ARE primarily P-T-O - meaning Position - Tag - Obstruction as our priority. We need to become P-O-T (never mind what the old hippie in me sez about this) with P being Position, O being Obstruction, and T being Tag. Get into position, watch for obstruction, and then look at the tag - and isn't this the actual order in which it happens.....
