Thank you for addressing my point
I see where you are coming from (and to be fair I never claimed the TMO doesn't know the laws), but I still think there was obviously a problem with the TMO's communication. The ref stated "I do feel there is a hand between the ball and the grounding". Rather than contradict him (or suggest it wasn't completely clear) he stated "It’s the English players arm holding the ball. It’s not the black players arm it is the English players arm." This completely irrelevant point clearly confused the referee (and me). The referee then appeared a bit flustered, then agreed to go with the TMO decision.
I do feel part of the problem lies with the way the TMO and referee now seem to debate these decisions. Previously it went straight up to the TMO who made the final decision. It was simple, and in my opinion the best way to do it. These days there seems to be a debate between the TMO and referee every time a decision is made. Sometimes the referee accepts the TMO's decision, other times they will completely over-rule the TMO. If we are going to continue with this system the role of the TMO and referee in these decisions need to be more clearly defined in my opinion, and importantly the discussion between the two needs to be clear and concise.
The referees initial statement was "I do feel there is a hand between the ball and the grounding". He doesn't mention whose hand it was because it was completely irrelevant. Perhaps the TMO was trying to be helpful in some way by stating it was an English arm, but all it did was completely confuse the situation.
I will state again I really don't have a massive issue with the TMO actual decision. I (and the referee) thought the ball was clearly held-up, but the TMO obviously didn't think it was 100% clear. The interaction between the TMO and referee was the biggest issue, along with the fact the wrong question was probably asked initially!
It was pretty easy to prove it wasn't a try by watching the video
Again, that's not the point I've been trying to make, so I should probably give up!
