Looking for a Toe

[sseltser]

I had a game this past week (2 official) and this occurred.

Ball is moving around perimeter and as lead I'm looking through the action of people cutting through the paint. Guy catches and squares up near the top of key slightly towards the strong side and I notice that his feet are on the line. After the shot goes in, I notice my partner was as deep as the 28' mark and maybe deeper and is signalling a three. I whistled it, told the table that it was a 2, administered the throw-in and along we went.

The def. coach (it was in the 1st half and right in front of his bench) told me it was a "good call" (of course he would, right?). At halftime, my partner thanked me because he couldn't see it (so he guessed, apparently).

Questions:
Should the lead be noticing / looking for jump shooters feet?
If you were the T, would you be upset?
Should the L come out and change this call?

Any thoughts? Thanks.
