Two of KR, Salford and Wire only need to win two out of their last four games to leave us needing to win all four of ours. I'd say the season was done a while ago.
Just on Sinfield, Smith has made clear he doesn't like picking very young players, and some of the signings for this season were to add squad depth with players that were a bit older. I think its time to give Jack a go, but I respect Smith for wanting to protect teenagers.
