The defending WNBA champion Chicago Sky host the New York Liberty in this opening playoff game. There's a big class difference between the 26-10 Sky and 16-20 Liberty. The key question is the gap enough for the Sky to cover this number?

I say it is.

The Liberty did well to get into the playoffs. They accomplished the task by winning six of their last eight games. But none of these games was against any of the top five teams in the league. There's a dropoff from the top five teams - Sky, Aces, Sun, Storm and Mystics - to the rest of the league.

Chicago has a huge edge inside. The Sky led the WNBA with an average of 42.1 points in the paint. The Liberty was last in that category, averaging 31.2 points. Candace Parker and Emma Meesseman give the Sky a strong inside presence. Chicago finished No. 1 in the league in field goal percentage. The Sky also have much better depth and bench strength than New York.

The Liberty is highly reliant on star guard Sabrina Ionescu. But she can go hot and cold. New York ranked third-from-the-bottom in scoring. The Liberty did well to reach the postseason. But they aren't going to advance out of the first round.
