For the Tyler Harvey incident it was clearly Westley who was at fault as he prevented Harvey from getting the ball for our throw-in. He pushed Harvey for no good reason.
For the Mellor handball, the incident happened outside the penalty area (so how could it possibly have been a penalty?) and there were a couple of other Argyle defenders in close proximity (so not a clear goalscoring opportunity). The punishment for handball is a yellow card I believe (so what is the problem).
As far as the 8 minutes of stoppage time is concerned. First, it is notable that the referee played 4 minutes of stoppage time in the first half so it was already evident that he was a ref who, unlike many others, was quite prepared to add an appropriate amount of time to cover stoppages (in the first half there was the clash of heads that delayed play considerably). At the end of the second half he signalled 6 minutes of stoppage time but almost as soon as that period started a Stevenage player went down 'injured' for at least 1.5 minutes, so it is entirely consistent that there were actually 8 additional minutes.
I found it completely refreshing that the referee actually added on a significant amount of time at the end of the game to account for injuries, substitutions and time wasting. People around me were commenting throughout the game that the referee needed to get a grip and stop Stevenage from time wasting but, in truth, there is little that a referee can do to prevent it other than i) booking players and ii) adding time on at the end. Given that pretty much every Stevenage player was wasting time throughout the game it would have been difficult for him to single specific incidents out and book particular players so adding time on was exactly the right thing to do.
Graham Westley has absolutely no case. Last night was a great example of the saying 'you reap what you sow'.
