Seattle Storm vs. Phoenix Mercury Prediction
I’m on the Storm and the points in this one. Just plain and simple, I don’t think the Phoenix Mercury should be laying points against anyone, even if they’ve managed to be competitive against some of the better teams in the WNBA this season. The Storm only lost the first meeting by 4 point and while the Storm have been one of the worst teams in the WNBA this season, so have Phoenix but with a lot more expectation which makes them the biggest disappointment in the WNBA as well this season. I’ll take Seattle and the points here by default.
