The other strange thing I noticed is how many goals have been reverted due to video analysis (mostly offside situations). Maybe I just haven't watched enough soccer recently, so I didn't see that trend earlier, but I found it curious. Maybe the two are connected, with defensive players trying to enforce offside situations by playing back into their own direction, and accidentally hitting the own goal more often than before. Or that the technology and its more frequent use allows for more precise detection of who was actually last to touch the ball (sounds more reasonable).
