CMHCoachNRef wroteActually, coaches, players, and frequently, spectators refer to the lines at either end of the floor to be base lines.
As officials, we refer to them as end lines. I will frequently tell the player "You can run the end line -- I am going to hand it to you and get out of the way (assuming the other team is pressing). Of course, they know those lines as baselines, but that is OK. I have never heard a coach yell "no end line", but I frequently here coaches yell "no baseline." As a referee, if you think that statement implies that you should be looking for chalk to be kicked up, you are likely mistaken.
I completely understand. How "they" refer to it is none of my concern. How we refer to it is.
I haven't been doing this as long as some. My mentors try to teach me the "right ways" to do things. I read the books, practice, and go to this Forum to get better and learn. I still have a long way to go but like to think I'm getting better.
My point to new refs is this - learn to do things right the first time and use the right terminology not what coaches, players, spectators use. Help dispel all those myths we constatnly talk about. Be a part of the solution, not a part of the problem.
Billy Joel once wrote; "Get it right the first time it's the main thing. Get it right the second time, it's not the same thing." (or something close to that).
Off soap box.
