Three key pieces to last season’s success are coming back for another run in 2020.

Stefanie Dolson, Courtney Vandersloot and Allie Quigley have agreed to re-sign with the Sky.

After getting off to a slow start in free agency, the Sky got down to business Thursday.

Three key pieces to last season’s success are coming back for another run in 2020, along with a dynamic new backup point guard.

Allie Quigley, Courtney Vandersloot and Stefanie Dolson agreed to re-sign with the Sky, a source told the Sun-Times. All three deals are expected to be announced in the next few days.

The Sky also announced the signing of former Aces guard Sydney Colson. Terms of the deal weren’t released, per team policy.

The returns of Quigley and Vandersloot come as no surprise. They were married in December 2018, bought a house near the Sky’s practice facility in Deerfield and had expressed their desire to return after last season’s heartbreaking second-round loss in the playoffs to the Aces.

“Obviously [with] how last season ended, I feel like I owe Chicago a true commitment to them, and I told [coach] James [Wade] that after the season,” Vandersloot said last month. “So there’s nothing up in the air about that. Right now, it doesn’t even feel like an offseason or free-agency season to me.”

Bringing back Dolson seemed inevitable after the Sky traded Astou Ndour to the Wings this week.

Dolson has grown as a stretch five in the last six seasons and is a major factor in the team’s overall chemistry. In 2019, she averaged 9.3 points and 5.6 rebounds.

The addition of Colson, a speedy ballhandler, signals that the Sky might be moving on from restricted free agent Jamierra Faulkner, who is recovering from her fifth knee surgery in four years. It also could mean that guard/forward Gabby Williams, who accepted the role as Vandersloot’s backup last season, will play more minutes at her preferred forward positions.

Last season, Colson, the 16th overall pick in the 2011 draft, averaged 3.3 points, 1.8 assists and 11.5 minutes in 33 games.
