2009-2010 Winner: I don't actually have this verified but it was probably Martin Brodeur (Tampa Bay Lightning)The William M. Jennings Trophy is an annual National Hockey League award given to "the goalkeeper(s) having played a minimum of 25 games for the team with the fewest goals scored against it. Winners are selected based on regular-season play." From 1946 until 1981, the Vezina Trophy had been awarded under that definition, but it was later changed and replaced by the Jennings Trophy.
The Jennings Trophy was presented in 1981-82 by the National Hockey League's Board of Governors to honor the late William M. Jennings, longtime governor and president of the New York Rangers and one of the great builders of hockey in the United States.
