I think most people define bottling it, or losing one's bottle as meaning losing one's nerve, or acting in a cowardly manner, for what it's worth.
No one, as far as I can see, is suggesting that ref's should be taking risks, when they are not certain about decisions, so I don't know why you raise that point.
All I am doing is responding to an earlier post, by Tom, and I have asked him to define what he means, when he accuses ref's of bottling decisions, because he becomes very defensive, and offensive, when others criticise refs.
Below are two quotes made by Tom, during Sunday's game.
"That should have been a pen and red for Lovren."
"He bottled it completely."
These were made in reference to the Long/Lovren incident on Sunday. I just want to know if he thought the ref was cheating, or showing bias, or if the ref was correct in doing nothing.
