I disagree - at the high school level, there are enough violations that happen where widening your view seems to make sense.

On a first of two (or three) shots?

This observation is based on officials doing high school level and below:

Officials who stand in that vacated lower lane space during the first of two free throws inevitably follow the flight of the ball to and though the rim.

That habit then far too often carries over to the second free throw even when the official stands in the proper space, much to the detriment of proper observance of those lane space players for whom he's responsible.

This, not merely anecdotal, but based on video evidence.

The NFHS mechanic serves high school level and below best.

Just do it. Just train others to do it.

Down here, we have adopted Women's floor coverage for about 15 years. The L getting out to the corner isn't that big of an issue (unless you are working with a Men's official) but getting the T engaged into the post is fruitless. That call is still being made by the L peripherally or by C expansion.

When discussing this, every T "claims" that they are engaged in post play but not many off ball calls are being made out of that position with regards to post play.
