6 — Current or incoming WCHA student-athletes centralized with national teams in preparation for the 2018 Winter Olympic Games: Wisconsin’s Annie Pankowski, Minnesota’s Kelly Pannek and Minnesota Duluth’s Maddie Rooney (U.S. Women’s National Team); and the Badgers’ Emily Clark, and the Gophers’ Sarah and Amy Potomak (Canada’s National Women’s Team).

9 — The number of shutouts in 2016-17 posted by Syracuse’s Abbey Miller and St. Lawrence’s Grace Harrison, the most of any returning netminders.

16 — Clarkson returns 16 letterwinners from last year’s team, which went 32-4-5 and won the program’s second national title in four years.

16 — Number of September regular season games in Wisconsin history, in which the Badgers are a spectacular 15-0-1.

56 — The amount of points scored last year by St. Lawrence senior Kennedy Marchment, the most of any returning player.

81.8 — Rensselaer returns 81.8 percent (81 of 99) of its goal-scoring for a season ago.

874 — Combined coaching wins that will be behind the benches this weekend in Madison, when No. 2 Wisconsin hosts Mercyhurst. The Lakers' Michael Sisti ranks second in NCAA Division I women's hockey history with 444 victories during his 19 years at Mercyhurst. Badgers bench boss Mark Johnson ranks third with 430 wins in his 15 years with Wisconsin.

1,135 — Saves in 2016-17 by second-team All-American Kassidy Sauve, the Ohio State single-season record and just three shy of the WCHA standard. After ranking among NCAA leaders for save percentage (fifth - .942), minutes (sixth - 2098:20), shutouts (tied for seventh - six) and goals-against average (16th - 2.00), the redshirt-junior is the coaches' choice as preseason WCHA Player of the Year.
