The Blackhawks are playing better lately. But they still aren't a good team. The marketplace has bet the Blackhawks into a high enough range where I see enough value to back the Sabres.
Buffalo halted a six-game winless streak with a 4-2 victory against the Senators Saturday. That should provide the Sabres with a much needed confidence boost. 
Chicago also is coming off a Saturday victory, beating Nashville, 7-2. The Blackhawks' victory is misleading, though. They were outshot, 41-24, by the Predators. 
Buffalo has been tough vs. below .500 foes winning 10 of the past 14 times in those situations.
