It's a case of sibling rivalry meets sibling revelry.
Belle Plaine enters this week's Class 2A, Section 2 volleyball tournament as the top seed in the north bracket. The Tigers are under the tutelage of former star Cassie Wolpern, who in 2002 ended her varsity career there with a then- national high school record 2,638 kills.
"[Having] a bit of an extreme competitive nature when I played, I didn't know if I would like it or if I'd have too much of a player's mindset," the second-year coach said. "But being back in Belle Plaine with all of my experience and knowledge of the game, I felt it was my obligation to share it."
Some personal connections to the team intensified the itch.
Wolpern's younger sister, Abby, and cousin Haley Fogarty are the leading hitters on this year's team, which opens section play Thursday against Sibley East.
Cassie Wolpern previously coached Abby in the junior club volleyball ranks.
The nine-year age difference between Cassie and Abby means the two didn't grow up fighting over the same toys, but the situation of a sister-sister coaching relationship is a unique one.
"Obviously we have our ups and downs but it's been a lot of fun," said Abby, a senior middle hitter for the Tigers. "For the most part, we deal with it pretty well."
