It might be key again heading into a third straight postseason series between the Central Division rivals, which starts at United Center on Friday in Game 1 of a Western Conference Second Round series (9:30 p.m. ET; NBCSN, SN, TVA Sports 2).
The Blackhawks, who struggled to kill penalties at the end of the regular season, didn't improve in their Western Conference First Round series against the Nashville Predators. They rank 13th among playoff teams, allowing six power-play goals in 22 times shorthanded (72.7 percent) and know they have to improve quickly. The Wild scored four power-play goals in 12 opportunities against the St. Louis Blues in the first round and their 33.3 percent success rate leads playoff teams.
"When it doesn't work you always try to make some adjustments," Blackhawks center Marcus Kruger said Wednesday after practice. "We're not happy with how that series went in [the penalty-killing] aspect, but we have a new chance here playing Minnesota. They've got a good power play, so we have to get better in that area to be successful."
