The Blackhawks' defense is slipping and so is goalie Kevin Lankinen, who was outstanding earlier in the season. Chicago is giving up an average of 4.8 goals during its last five games.
Now the Blackhawks face their worst opponent - Tampa Bay. The defending Stanley Cup champions have averaged 5.5 goals in going 4-0 versus Chicago this season. The Lightning lead the NHL in scoring at 3.6 goals a game. They've scored 4 or more goals in five of their last six games. 
However, the Lightning's defense has not looked good. Tampa Bay has surrendered at least 3 goals in each of its past seven games. The Blackhawks have a slightly above average offense, but the league's No. 3 power play unit.
