New York Liberty vs. Phoenix Mercury Prediction

I’m leaning towards the Liberty here. Perhaps New York is more banged up than they’re letting on, but this is still a Liberty team that’s already won on the road in this series, and at a certain point, i have to think that hte experience plays a factor. Not to say that Phoenix doesn’t have it, but the Liberty just played in a high-stakes winner take all game five in the WNBA finals last year and came out smelling like roses. I think that has to count for something and to get a free bucket with the defending champs here is good enough for me. Give me the Liberty and the points.

Chris Ruffolo's Pick: New York +3
