It's probably the perspective, since it's shot at an angle towards the midline. They, and all the other 2 balls, come incredibly close, but I'm sure all of the teams are well aware that they can't cross the midline.

We have about 3/8" of tolerance between being too far away to grip the edge of the ball and being over the line. Since the intake is pneumatically actuated the drive team can force it to the down position temporarily during set-up to make sure they are in that zone. We checked the line with a right angle tool when designing the auto routine to make sure we were clear. The drivers are familiar enough with it now to eyeball it accurately.

It is certainly close to the line and the movement happens quickly. I don't envy the referee who has to consider the legality in the heat of the moment, and we would love the opportunity to flex the intake down during the pre-match set-up to any curious ref.

One of the easier ways to judge is to picture a 1" stripe on the crown of the ball and see if the intake encroaches on that stripe. If the word FIRST that is printed on each ball is placed at the top in line with the center stripe it is even easier to judge.

As a first year ref, this makes me happy.

Gonna have to remember this, and possibly this is something that should be passed on to other refs...

We had not yet developed it before Smokey Mountains.
