IAABO OOB mechanics

How can the lead have a decent view if he's not even looking over there because it's outside his primary coverage area? He's watching post players, and defenders, banging around in the paint, maybe watching for three seconds. He's not watching the point guard about to step on the sideline boundary above the free throw line extended, maybe near the division line. That would be ball watching.

Granted, this is a challenge for the trail, especially after a skip pass, but at least it's in the trail's primary coverage area.

Agree 100%.

Back in the olden days, IAABO used NFHS mechanics and had the lead's out of bounds responsibility include the entire sideline, all the way back to the backcourt endline. It was a simple guideline to follow, and would occasionally have the lead sounding his whistle for the out of bounds, and then asking the trail for help on the correct direction call. The simplicity was the best part of the mechanic, even if the out of bounds responsibility above the free throw line extended was clearly outside the lead's primary coverage area.

Then IAABO changed to IAABO mechanics and ended the lead's out of bounds responsibility at the free throw line extended. A lot of old timers, including myself, resisted the change. It required the lead, and the trail, to decide if the ball went out above, or below, the free throw line extended, definitely more complex then the old, simple, out of bounds responsibilities. Occasionally there would be no immediate whistle when the ball went out of bounds above the free the line extended, with both the trail, and the lead, thinking that the other was going to sound the whistle for the ball going out of bounds.

It took some time, but we're all starting to get use to the new out of bounds responsibilities. The topic is broached in almost every pregame conference. It's not a perfect guideline, but in the grand scheme of things, regarding primary coverage responsibilities, it makes a lot of sense.

2-person is a game of compromises. When the player gets that close to the sideline, the lead just has to give up the post momentarily and look up the sideline. That line itself is also the leads PCA. There is no way a T, even one who has great movement, will have the angle to see a player stepping OOB unless it is far OOB. A ball that is knocked out and lands in the first row, sure, but not one that goes 1" OOB.

I think it only makes sense when the ball is knocked OOB. I think it makes no sense when the actual question is whether the player stepped on the line or dribbled the ball on the line. The trail just can't see those things. There is no amount of responsibility shifting and understanding that will allow the trail to see something that isn't visible from any normal trail position. The only way that "might" work is if the trail came all the way across to get in line with the far sideline, effectively forcing a cross court rotation.

The only person who can reliably make determinations on whether a player has stepped on a line or not is the official who is looking down that line.

According to the old NFHS (I'm not familiar with the new NFHS guidelines), you are correct. The new IAABO guidelines have the lead's PCA, regarding boundary line responsibilities, only as far as the free throw line extended.

And, or course, half the time, both coaches have the best look at a player stepping on that sideline. Give both of them a "table side sideline out of bounds between the free throw lines extended only Fox 40 whistle".

Camron Rust: You're preaching to the choir. I really liked the simplicity of the old NFHS, and old IAABO, boundary line responsibility mechanics. I guess that IAABO wants to stress the importance of staying in one's primary coverage area, even in regard to boundary line responsibilities, and wants to avoid ball watching at all costs. I'm not defending IAABO mechanics, I'm just trying to explain their reasoning. In any case, I'm not a rebel, I usually do what I'm told, so I reluctantly use the new IAABO boundary line responsibility guidelines, after pregaming the heck out of them.

Well it is not the old mechanic from the NF, that is the current mechanic. The NF has never changed this mechanic to my knowledge because this has been the mechanic for the Lead to have the line on their side of the court all the way up the court.

Smart move on their part. All of our young officials are taught, and use, the "lead up to the free throw line extended sideline boundary responsibility guideline". Many of our veteran (read old) officials still use the (old, and current) NFHS "lead up to backcourt endline sideline boundary responsibility guideline". When a veteran works with a young partner, it can lead to problems that often happen in an area of the court where the coaches often have the best look. Bert Lance was right, if it ain't broke don't fix it.

So, IAABO has basically decided the more likely play that needs to be covered (player with the ball stepping OOB) is less important than a play 30+ feet from the ball since the trail can't cover that play and they don't want the lead looking for it.

And for that matter, taking a look at my line isn't ball watching if it is my responsibility. I'm not covering the defender, just the line. Sometimes, proper coverage leads to two officials looking NEAR the same area but not watching the same things.
