NRL Predictions for Round 22

By

Team Ratings for Round 22

These predictions are preliminary only, because game locations are mainly listed as TBA. The only games on the NRL site with an actual location are the home games for the Broncos and Cowboys. Yesterday the NRL even had the Warriors playing at home in Auckland, so uncertainty abounds. I have treated all the TBA listed games as being played on neutral grounds, except the Rabbitohs versus Titans which I have predicted as if it were a home game for the Titans.

I will update later in the week if things change.

The basic method is described on my Department home page.
