In this game, you have to be at your best every week or you will be found out, especially in his position. He's experienced enough now, having played 71 NRL games. He should know what to expect.
It's hard to know what influence the off-field issues are having on his game but if he can keep his home life in shape then it can only help his professional life.
Maybe it was the presence of Cowboys fullback Matt Bowen that brought out the best in him. If that's what motivated him, then there's an even bigger challenge waiting for him this week in the shape of Souths fullback Greg Inglis.
Locke should be pushing the boundaries to unleash his full potential every week and I am sure he will not be disappointed with the results. He should be saying in his own mind, "I'll show him". He should be excited about playing Inglis to gauge himself against one of the best players in the world.
It was a relief to see the Warriors win on Monday because, after getting so close, I'm not sure they would have coped very well if they had been beaten. That win will give them self-belief and a good reminder of what it takes to win.
The return of hooker Nathan Friend was critical, and it seemed like everything worked because he played at a different tempo. He made things happen and others were more confident.
A lot of the Warriors played very well but no one stood out amazingly. That's a good thing because it takes a team effort to win games, not just individuals, and everyone has to play to their potential to get the results in the toughest competition.
