The New York Islanders signed top-prospect Kyle Okposo to a three-year, entry-level contract on Friday. Okposo, currently playing for the United States at the world junior tournament in the Czech Republic, reached a deal with the Islanders just more than a week after he left the University of Minnesota. He will join the Islanders' organization, which selected him with the No. 7 pick in the 2006 NHL draft, after the junior tournament is over. The 19-year-old right winger from St. Paul, Minn., already has a goal and two assists in two games with the American team. Okposo earned an assist Friday in the United States' 4-2 victory over Switzerland. He will earn $850,000 each year of the deal and is eligible for bonuses that could reach a maximum of another $850,000 per season.
