1. The Lightning put together an impressive response after a tough overtime loss. After dropping the first game on its road trip 5-4 to the Wild on Saturday, it put together a terrific offensive performance in beating the Blackhawks, including an NHL-record 33 shots on goal in the second period.
2. Louis Domingue continues to show he's more than serviceable as the backup goaltender. Facing the team with the third-most goals in the NHL before Sunday's game, Domingue stopped several point-blank opportunities that he probably should not have stopped. He made 33 saves on 36 shots.
3. The Lightning penalty kill impresses again, this time setting a franchise record. When Tampa Bay killed off a second first-period penalty, it had killed 27 straight penalties to open the season. The streak ended at 27 in the third period with a Blackhawks power-play goal.
