Washington State QB pick: Caden Pinnick Over 0.5 passing touchdowns

ProphetX probability: 50%

Cougars QB Caden Pinnick faced Washington in Week 1 last season while playing for the UC Davis Aggies in the Big Sky Conference. Pinnick completed 8-of-16 throws for 50 yards with one touchdown and one interception in a 70-10 loss. 

Logically speaking, Pinnick should be surrounded by more talent at Washington State since UC Davis is an FCS program. Also, Wazzu threw two touchdown passes vs. the Huskies last year, and Washington's defense is projected to be as good this season. 

Washington QB pick: Desmond Williams Under 17.5 completions

ProphetX probability: 49.5%

Huskies QB Desmond Williams had fewer than 17 completions in two of his three games against non-conference teams last season. Both were blowout wins for Washington: 70-10 vs. UC Davis and 59-24 vs. Washington State. 

Our path to cashing this prop pick is the Huskies trampling the Cougars with their rushing attack and putting in their backups in the second half if they have a big lead. 

For what it's worth, nine of Washington State's 13 opponents last season completed 16 or fewer passes. However, the Cougars hired a new coach this offseason and only have three returning defensive starters.
