As the NWHL free agency period came to a close this weekend, 22 women who played their college careers in the NCAA had signed contracts to join the league as rookies. Most of the new class are recent college graduates, but four women -- Lisa Chesson, Anne Schleper, Jordyn Burns, and Kristina LaVoie -- have been out of school for at least a year.

Chesson and Schleper are former Olympians and bring a wealth of experience to the league. The new class also includes two Patty Kazmaier winners -- Amanda Kessel and Alex Capenter -- as well as 13 women who've played in an NCAA National Championship game.
