By my count there were 11 current or former WNBA players in that game.
UConn: Samuelson, Nurse, Williams, Collier, Chong, Dangerfield
Maryland: Destiny Slocum, Brionna Jones, Stephanie Jones, Kaila Charles, S. Walker-Kimbrough
That Maryland team was very good, 32-3 overall. Saw them in Bridgeport that year in the Regional Semi-finals against Oregon, who was led by first year standout Sabrina Ionescu. The game was at noon, I think, and Maryland did not come ready to play. Oregon smoked them, only to then get smoked themselves by UConn in the Regional Finals.
