In NCAA-W, if the ball is in the L's primary, then the L has responsibility for the 5-sec. count.
I have been told many times by various veteren officials that in NFHS, the L never has a 5-sec. count, but I have never been able to find that specified in the mechanics manual. The same veteren officials have never been able to tell me who does have the count, if the ball is on the low block, directly in front of the L. Does the T have the count, while the L watches for fouls and violations? Do we really have 2 sets of eyes on-ball? Who's watching T's area? The only answer I've been able to receive is, "A 5-sec. call never happens in that spot, so don't worry about it." So, when I work with them, I guess I don't worry about it.
