With 20-30 cameras covering major games, we're seeing many things which escaped our attention previously. And with that comes intense scrutiny of every incident, in painstaking detail. Such a team should have had a penalty because slo-mo replays showed that there was the slightest contact between x's bootlace and y's ankle; on the eighth viewing of the still images from nine different angles, it appears that the whole ball did cross the line by 0.0125mm etc etc. Personally, this detracts from the enjoyment of the game. You'll finish up neurotic bemoaning all the incidents the ref missed (because he's human) yet were picked up by the latest technology available to Sky after 45 minutes painstaking analysis by an engineer.
