Irish men's basketball captain Rob Kurz rooted against the Notre Dame women's team on Wednesday night.
It wasn't because he doesn't have school spirit. It's because his sister, Laura, was playing for the opposing Villanova Wildcats.
And it was a big night for Rob. He was watching his sister play college hoops for just the second time ever.
"It's really rewarding," Rob explained from his seat behind the Villanova bench. "We're really close and we talk all the time. We're only a little more than a year and half apart in age."
"So we grew up together, playing together and she'd helped make me a better play," the older Kurz said.
Because it was only the second time he's seen her play, Laura says she put added pressure on herself to play well.
"I was really nervous because a lot of family came out," Laura said after the game. "Just playing in front of him makes me nervous."
"He rarely sees me play so I felt I had to show off a little bit."
Laura played very well, leading all scorers with 20 points.
And make no mistake, Rob wasn't cheering for Notre Dame on this night.
"It's family," Rob said with a smile on his face. "I have to cheer for her."
The roles were reversed on Tuesday. Rob was on the court leading Notre Dame while Laura was in the stands cheering on her brother.
Since Rob's opponent was Cincinatti and not Villanova, it made deciding who to cheer for pretty easy for Laura.
Laura transferred to Villanova from Duke. She's now real close to the family's home outside of Philly.
So does the extra practice on the home basket give Laura the advantage in a game of horse against Rob?
"I think I would win now," Laura said. "Back in the day he probably would have beaten me."
"What did he say?" Laura then asked.
"I would say it's about 50-50, but that I win more of the times," Rob said.
When told of his response, Laura wasn't surprised.
Ahhh...the friendly sibling rivalry.
