I would've waited another 8-10 rounds before giving him an extension on the proviso that we had more 'W's that L's. Still though, he seems to have the roster he wants and Penrith have been very competitive this year. I think knowing that things are set beyond this year can only halp the side this season. I still wouldn't have extended his contract yet though.
Too early in the season to be offering a coach a contract extension, although they could just as easily sack in a few months anyway.
