The offside call that started the rabbit hole

3:49>> Um so I've been watching a lot of the games, and I'm going to start with some the first thing that actually got me going down this rabbit hole of technology behind the World Cup. I was watching the game with England versus Croatia in the group stage, and at like right before halftime, Croatia got an equalizer right before the half to make it 2-2. Ivan Perišić delivered a perfectly weighted pass to Petar Musa, and from this perspective, it looks offside to me. That Petar Musa is the blue shirt right outside the the bigger box, whatever that's called. Um and he seems to be on this side of all the all the English defense.

4:29So, then we can go into the the next photo, which shows the actual judgment, right? Um looks offside to me. >> [laughter]
