Seattle is the top defensive team in the WNBA ranking first in 3-point defense and second in scoring defense and defensive field goal percentage. The Storm have held their last four opponents to an average of 70.2 points. The Sky could be without double-digit scoring guard Courtney Vandersloot, who is questionable due to a concussion. She missed Chicago's previous game this past Saturday against the Wings in Dallas.

The Sky have limited their past three opponents to an average of 74.6 points. They rank No. 3 in defensive field goal percentage and fourth in scoring defense.

Another key factor to the Under is the early start time, which is 9 a.m. West Coast time for Seattle. The Storm has been on West Coast time for the last two weeks.

The Sky hasn't played since that road win against Dallas, which was five days ago. So they could be rusty.
