I don't agree with Wycombe-like tactics of cheating, simulating injury and wasting time.
I do believe that if you feel wronged, it is worth making your point vociferously.
I also believe that referees, when they know they have made a mistake, are likely to try to atone.
Today, a Pompey player hoofed the ball away after play had been stopped. It looked a clear caution, and was not given. I did not see which player it was, but others have suggested it was Gareth Evans, who was already on a yellow. If so, he should have walked.
Derek Adams loudly made his point, and was booked for his reaction.
If the ref did bottle (don't like using that phrase, but can't think of an appropriate alternative) the decision to give Evans a second caution, and compound this with Adams' booking, I suspect it niggled away in his mind.
The next decision he gave was a foul on Songo'o, which from my angle looked a good tackle. Carey stepped up and curled in an equaliser.
Funny how it goes.
