To lag or not to lag

[Mark Dexter]

As a timer, I understand how frustrating this can be, but lag time is the rule.

I also had a hard time understanding the difference between 5.10.1B and 5.10.1D (the play from this post). In D, the official is looking right at the clock when the whistle blows. In B, s/he looks at the clock after blowing the whistle - the NFHS uses the time taken to look up as lag time, so there is no double lag time allowance (i.e., whistle at 2.0, look at 1.0, stop at 0.0 and horn).

Hope this helped.
