Bill Mosienko would make a relatively quick debut into the National Hockey League at the age of 20 in the 1941-42 season as the events of World War II would deplete the rosters of the premier league of Hockey.  Dubbed “Wee Willie” due to his short stature, Mosienko would blossom in the 1943-44 season with a 70 Point season and the season after would see him paired with the Bentley brothers to form the “Pony Line” a moniker derived from all three of the players being a little vertically challenged.  The trio would become one of the best lines in the NHL, and Mosienko would benefit with a pair of Second Team All Star Selections (1945 & 1946).

A career professional with the Chicago Black Hawks, Bill Mosienko may not have won a Stanley Cup in Chi-town, but he was an excellent forward who played in multiple All Star games. Mosienko was also a very classy player (he only ever had one fight in his NHL career and was rewarded with the Lady Byng Trophy in 1945. Winning that accolade was nice, but he also a perennial fixture on the annual points table and was one of the better players in Chicago when they were not exactly a league power.
