"Used and administered this system extensively for a high level youth soccer team over the course of a few years.  It was much better when they were using on-player trackers, small gps enable motion sensors that players slotted into a sleeve on their dominant foot. This allowed every touch on the ball to be recorded and put in a play list. This was the real value of the system: Compressing a 90 minute game into a list of watchable moments that could be reviewed incredibly quickly. The trackers were small enough to be non-invasive and rarely came out or got lost. They do require more on field management as they are kept together in a charging case that also downloads the data, so they need to be pissed out and collected every game. Not a big deal. There were some issues with reliability mostly due to contact issues in the case, likely exacerbated by sweat, but those were manageable with care (cleaning, monitoring) and having a few spares. There was some additional  administrative overhead of assigning trackers to players, but not a big deal. They could be reassigned  on field using their app or even after a game was recorded. I suspect the real reason they did away with the trackers was cost. Now the system is just the camera with AI tracking of players. It's unfortunate as the new system doesn't provide the same accuracy of tracking and is completely devoid of the most important feature of player moments. Without which you have to scan the entire video manually. Perhaps this will improve with time, but the value and utility of the system was so much reduced that players stopped using it. Very sad as it was an important tool for improvement. "
