Stokes, a junior, is the only returning starter from last year's defense, which posted 14 shutouts and gave up only 19 goals.
While Saturday's game against Connecticut is just an exhibition, Stokes views the match as a chance for the defense to get a feel for itself and to learn to play more effectively.
"We're not too comfortable with our new defense," Stokes said.
The defensive formation changed from a three-man backfield to a four-back set this season, Stokes said. But the change in both formation and personnel does not worry him.
"I'm not concerned," the All-America candidate said. "I'm more excited. I think we have the potential to be just as good (as last year)."
The usually reserved Stokes said in order to get the defense to last year's level he must be more of a leader on the field.
"I think I'm definitely going to have to be more vocal in the system we're playing, so I'm going to have to work on that," Stokes said. "I hope to be a leader by example also, and just try to incorporate both."
Bolowich remains unsure who will line up in the back, but agreed Stokes must make himself heard.
"He needs to communicate more," Bolowich said. "He needs to be more consistent and establish himself as a dominant defender."
