Ball becomes dead

[Texoma_LJ]

After returning to the striped shirt after a little over 15 years, some things have changed, alot for the better.
One thing that has changed though from my previous years I dont see much anymore is this use of the arm signal marking a dead ball (arm up) on each play. This is a highly effective tool to indicate when a ball has become dead, when a whistle is avoiding your hand, or the little ball is frozen inside.
I was curious how many officials still use this as common practice, if it is no longer accepted as common practice, or I am just one of the few that see this as a good mechanic especially as an LJ.
Sure does let the coach on the far side know what I'm thinking quickly !!
