I'm going with the Bulldogs against the Broncos tonight.

Friday, the Dragons over the Roosters.  The Warriors over the Knights (will be the match of the day).  Storm over the Rabbitohs.
Saturday:  Cowboys to trip up the Titans.  Sea Eagles narrowly over the Panthers. 
Sunday:  Raiders over the Dolphins (only just).  Wests Tigers to come close against the Sharks.
