In her second year, deRoeck has developed into a steady force on the back line for the No. 11 North Carolina volleyball team, while growing into a new role on the team.
DeRoeck is UNC's libero. A new rule implemented in collegiate volleyball this year states the libero must wear a different colored jersey from the rest of her team.
The libero is allowed to substitute for any back row player without costing the team one of its 12 substitutions per game.
The libero is not allowed to block, attack a ball above the net, or most importantly for deRoeck, serve.
"Its allowed us to have a strong defensive player in the back row all the time and not have to worry about the substitution numbers," said UNC coach Joe Sagula. "The only downside is that they don't get to serve, and Caroline has a great serve."
DeRoeck said she has adjusted easily to the new role and that it has helped her performance this season.
"Its easier to stay in tempo; you're only out for a couple plays, and you're still in rhythm (when you get back)," she said.
Sagula said the new rule has been well-received by the team and most people involved in the sport.
He said it gives the team more consistency knowing there is always someone back on defense and has allowed him to use more situational substitutions.
