The best recent example of a significant video tech decision was at Murrayfield on Saturday - what looked like a 'game changing' Irish try quickly replayed by the video referee and the charging Irish player's foot identified to be touching the side line!! No try and Scotland pushed on from there. Sadly and retrospectively there have been footie refs' decisions that have been 'game changers' and are avoidable with proper action - less annoying if your team is the beneficiary but that's not the issue - it shouldn't be happening as regularly as it is anyway!
