The AFL yielded one upset and maybe an indication that Melbourne are decent this year.
The NRL also provided two results that were something of an upset and an indication that Cronulla have some significant issues.
Apart from that picking the NRL is straightforward while thinking teams could lose, while the AFL is a more difficult choice between two teams that could actually win.
