I'd love to believe him, but if life has taught me anything it's that people will usually do what's in the best interests of themselves. I'm sure he has aspirations to be the head coach next year and that would be playing on his mind no doubt. He would have come in initially with no pressure and expectation and just said to the players have a red hot dip, take the game on and tackle hard. Now that he has a decent chance of keeping the job it's only natural that he will start to do what's in his best interests.
Sounds like you aren't very trusting.
I don't trust the board and the club but, for some reason, I'm happy to give JB the benefit of the doubt.
