The Blackhawks are finishing up a three-game, western-Canadian road trip that, so far, has not been kind to them. The Hawks have lost the first two by a combined score of 8-2, and are losers of four straight overall after beginning the year 6-2-2. The Hawks did get a strong effort the other night in Edmonton, firing 40 shots - including 31 in the opening 40 minutes - at Oilers goalie Mikko Koskinen, but the rookie netminder stood tall, stopping them all for his first NHL shutout. … With 43 goals on the year - the fifth-most in the NHL - the Hawks, like the Flames, have little trouble packing the net. Keeping them out, however, has been a glaring issue, even with the two-time Jennings Trophy winner Corey Crawford back between the pipes. Crawford, who missed nearly 10 months due to a concussion, won three of his first four starts and looked to be returning to form. But after allowing 10 goals in his last two starts, the 33-year-old has fallen back to .500, sporting a 2.72 goals-against average and a .909 save percentage.
