If you aren't already doing that every time-out and intermission, you aren't going to start doing it just b/c players' numbers are up on the scoreboard.

You said in an earlier response that officials are the "you" in the following statement: Well-equipped gyms with modern scoreboards usually have the players who were in during last quarter so you can compare whether they properly subbed or not."
