Both Grand Valley State University swimming and diving teams will enter postseason play as a top 15 team in the nation, according to the NCAA’s most recent Division II rankings. The No. 15 ranked men’s team dropped three spots since the last poll, despite a trio of recent victories over ranked opponents. In the month of January, the Lakers defeated No. 8 Indianapolis University, No. 11 Wayne State University and No. 13 Nova Southeastern University. The women’s team currently checks in at No. 12 in the nation. Both GVSU squads began competition Wednesday in the GLIAC Championship in Canton, Ohio and will finish this Saturday.
