The Waterloo Black Hawks begin defense of their Clark Cup championship tomorrow night as they open their U-S-H-L season at Sioux Falls. Waterloo is coming off its first ever Tier-One National Championship. A big question for the Hawks is finding someone to replace goalie Kevin Regan who anchored Waterloo defensively as he captured the Clark Cup M-V-P award. Waterloo coach P.K. O’Handley talked says goalie situation features a three-way battle. Being the defending champs, O’Handley realizes his team will now go from being the hunter to the hunted. He says some of the guys don’t realize that yet, but he says they will in a hurry.
