He's had his moments of self-doubt this season, and when the University of Denver Pioneers hockey team went 3-4-1 in January while getting outscored 16-22, senior goaltender Adam Berkhoel knew he wasn't playing up to form. But then the team put together a nine-game unbeaten streak that propelled them into the post-season. Berkhoel had turned into a brick wall, astonishing teammates with his athletic play and evincing praise from coach George Gwozdecky. "He'll make saves that, for a lot of people, seem unbelievable," Gwozdecky said. "But for Adam, he does it on a regular basis." A 190-pounder from Woodbury, Minnesota, Berkhoel began his DU career in 2001 as half of the famous "two-headed" goalie (the other head belonged to Wade Dubielewicz) that shut down the top shooters in the Western Collegiate Hockey Association. Berkhoel started going it alone last season, and upon his shoulders rest the Pioneers' tournament hopes.
