Caroline is averaging 9.2 points and 5.2 rebounds per game, both second on North to Annie Tate, and has even made three 3-pointers.
She scored 16 points in the first half against Hampshire, showing her confidence in the post.
"With being a veteran now, with girls like Anna [Davern] gone, I had to step up and show that I belong," Caroline said. "Last year I kind of faded at times; it's like I wasn't really out there. This year I went out with the attitude that I wanted to dominate."
"She started for us last year, but she was really our third or fourth option," Tomczak said. "To be fair she didn't really look for her offense. We told her we needed 8-10 points from you, and great defense. She's grabbed by the bull by the horns. It's fun to see how much she's grown."
Big sister is likewise overjoyed to see that growth.
It's not uncommon when the two get home that Claire will ask Caroline to take a look at some film with her.
"I do like it a lot; I hope she likes it too," Claire said. "I didn't get to see her for two years, being all the way in Maryland. I didn't get to any of her games, to see how much she has grown as a player and as a person. It's great to be home, to share the knowledge I have about basketball."
Claire Jakaitis, a teaching assistant at Wayne Elementary and also a tutor, has gained a new-found appreciation for all the extra work coaches like Tomczak put in.
He's appreciated having her aboard.
"She has been a huge resource," Tomczak said. "She's so smart, she immediately commands respect. It's so cool that she gets to coach her sister."
While the two girls realize there's a line between coach and sister, the personal touch helps Caroline.
"She's my sister, she knows me better, she knows who I am outside of basketball," Caroline said. "She's playing in college, that's something I aspire to do. Having her being able to teach things is helpful."
