Washington State at USC picks and predictions
Prediction
USC 89, Washington State 71
PASS.
USC (-1400) will set you back 14 times your potential return, and that’s way too much risk for not enough reward. You cannot bet the Trojans straight up, and even as part of a multi-leg parlay it makes little sense. Betting such heavy favorites over the long term is a losing betting strategy.
USC -15.5 (-102) is worth playing lightly. Washington State is just 1-3 ATS in the past 4 games, and 3-6 ATS in 9 games against Division I opponents.
The Trojans have managed just a 2-5 ATS mark in the past 7 games, so there is concern. And, USC has failed to cover the past 2 as a double-digit favorite, so tread lightly.
OVER 158.5 (-110) is the lean, but go with a half-unit play at best.
The total has gone high in 5 in a row for USC, so that’s what is driving this Over train. However, go lightly here, as the Under has cashed in 3 in a row for Washington State, with the Cougars mustering 64 or fewer points in each of the past 3 outings, averaging 61.7 PPG in the span.
