Yes OMC, I watched the game. And what you are saying is totally true, there's nothing can be done about blokes who make bad decisions like that one. Your last paragraph is totally on the money. But I think that it was about more than just the actual lack of execution by Smith.
The top teams seem to get away with having the lesser fill in players because those players not only know their job but carry it out to the letter. I am starting to think it comes back to the systems the team has in place, which come from the coach and leadership group (or at least should). I'm a big fan of what BA has done in the last 4 years and I think he should be the coach in 2019. But I am starting to question whether he has dropped the ball a bit this year. If a player can be out of form, maybe a coach can too. All I'm saying is that in a team where everyone knows their job and does it and doesn't stray from that, those mistake shouldn't get made by the back up half/hooker/fullback/utility or whatever the f**k he is, who has been on the field 5 minutes in a game where all we needed was a bit of smart management to get us over the line.
