He says he is pushing Foster to be more aggressive. She will likely be teamed inside with 5-11 sophomore Jayna Hurst, who skipped basketball last season to focus on volleyball.
"She's a very hard worker," Calabrese said. "We've always been kind of guard oriented but I think we will have a real post presence this year."
After strong freshman season, Hairston struggled last season.
"She had a little sophomore slump," Calabrese said. "She is very hard on herself and has a tremendous work ethic."
Hairston will be expected to pick up some of the slack for the offense lost to graduation.
"She has the potential to have a really good year," Calabrese said.
The lone senior on the squad is Jahneece Clements, a 5-5 forward, who is in only her second year of high school ball.
"She did not get much playing time last year," Calabrese said. "But she really came on this summer."
After losing their first four summer league games, the Cougars came back to win their final six. In a fall league they posted a 10-2 mark.
Some players from a quartet of freshmen are expected to fill some of the holes in the lineup with there being a good chance a couple of them will be in the starting lineup when the season opens.
"If we can start out okay then come January and February hopefully we will hit our stride," Calabrese said. "Once you learn to win it becomes contagious."
