Simple enough.
But let's not, for the sake of a mechanic either cherished or detested, overlook one significant thing: It's a legitimate PCA issue more than anything. I.e., after distributing the ball to the thrower, what kind of surveillance is the administering official providing?
New officials, particularly, are -- I think due to an engrained habit picked up by the legitimate two-person mechanic -- inclined to focus on the player defending the thrower and the thrower him/herself to the detriment of low post play. Lead's focus on the torsos and the elbows of players in his primary away from the throw-in goes lacking. This is the problem seen also with many Lead officials doing three-person who bounce the ball across the corner. Rather than pass the surveillance of the thrower and defender there off to the Trail and turning attention inward, his/her need for avid attention on the jostling going on in his/her primary down low is ignored.
This is observed time and time and time again with new officials. Enough that it's just a lot easier maintaining the correct three-person mechanic stated above and teach the Lead to look inside during the throw-in, unencumbered by the perceived need or lingering habit to look at the throw-in outside his/her primary.
Good officials at Trail can easily perform this prescribed mechanic and they are observed doing so regularly without incident. There's really no good reason, other than personal preference and perhaps expediency, to vary from the mechanic, if that's what you're asked to follow.
Is this a legitimate point?
