Probably been said before but I honestly think that when referees make decisions like Friend's they need to come out into the open and explain why. Not be interrogated, but simply explain why they gave the decision they did, to inform and educate all involved.
We all know the rule about elbows - players, managers, fans, refs.
Then Friend breaks those rules and does something different.
Surely it makes sense for him to explain why he did that in this instance! Why didn't he follow standard procedure?
With the best of intentions it would make everything clearer for all of us! We're the paying customers ffs, and players and coaches need to know what the rules are and how they are applied.
Rocket Science it ain't!
