Technology may still be cheaper than 2 extra refs. 2 extra refs have
been pretty useless in the Europa League last season.

Cameras need to be staffed too and other technologies only address some
types of errors. I keep reading about the uselessness of additional refs
during the trials in Europa League but I don't see how an extra ref behind
the goal could have missed the most egregious miscalls we see in the box
(Lampard's (non)goal, Given's take down of Anelka, Henry's hand, etc ..).
Perhaps it has to involve a rethinking of ref hierarchy and decision making
process as well so that sideline ref actually take reponsibility for what
they see. I'd like to see what were the directives to ARs during these
trials and findings. If anyone has a link I'd be grateful.

Note that I am not necessarily opposed to using video to help refs make the
right decisions on the most obvious calls (i.e. with rapid enough decions
making that wouldn't disrupt the flow of the game) but it wouldn't solve
most errors (perhaps 50%? including offsides, goal line, and obvious fouls,
hands, etc..).

They did miss similar incidents.

US High schools still use a two referee system on and off. First year I
refereed there it's incredible how one defers to one another on calls that
we should make. After that I just called everything I saw, even if closer
to the other blind guy, but it takes knowledge of the team to be able to do
that.

Even on the standard diagonal system, ARs refrain from calling a few fouls
that are "obviously" the CR's responsibility. I can see the extra referees
(GR, goal-referees?) deferring to the CR a lot in the future, until everyone
gets comfortable with the system, but not useful to catch the few balls
that bounce in and out. A pair of cameras broadcasting to the 4th's iPhone
should be enough to appease the one month in four year fans.

It'd be nice to see numbers to understand what they missed.
