08:30 AM ET 03.05 | It's that time of year again. If it's the stretch run of the season, the Blackhawks must have a new No. 1 goaltender. Ray Emery has displaced Corey Crawford as the Hawks' starter and has run off three consecutive victories, including a 23-save performance in Sunday's 2-1 victory over the Red Wings. Last season, Crawford took over for Marty Turco as the starter, and in 2009-10, Antti Niemi seized the job from Cristobal Huet and backstopped the Hawks to the Stanley Cup. "It's very unusual," said coach Joel Quenneville, who has been behind all three changes. "Once is probably plenty, twice is a lot and three is unusual. I just think it's all coincidental and it's the way it seems to be working."
