I think the main complaints about VAR in football have been the amount of time these decisions take and the inconsistency of the rulings. Instead of the constant play we used to have, now we see players stand around as the screen shows lines drawn in seemingly arbitrary locations to decide whether or not an attacking player was onside before a goal.

In contrast, fans have been fine with the goal-line technology, which gives decisive (usually) and quick results.

The use of AI in this paper seems more relevant for setting team strategies and picking players rather than enforcing rulings.

VAR could be used in situations where it is quicker.

For example, in basketball, it should be able to do goal-tending in near real time. Also 3s in the key.

The holy grail though is if it can help charge/block calls. Or we should consider changing the rule so that it can be consistently called, but that's a topic for a basketball forum.
