Ever since the bunker review was introduced it just feels to me like there has been a reluctance on the part of refs to issue straight reds. The idea of letting the game flow is good and I'm sure that most bunker review calls are fair but it does seem like an easy way to pass the buck to the TMO in a sort of hedge your bets type decision. The next ref who opts against a bunker review and correctly gives a straight red will have my respect.
