Healthy Patrick Kane impressing Blackhawks coach Luke Richardson with subtle plays

It was Patrick Kane’s fifth game back in the Blackhawks’ lineup Sunday since missing three with a lower-body injury.

Coach Luke Richardson said he hasn’t asked Kane about his health a lot, nor seen him shy away from anything on the ice. Most important, Richardson thinks Kane is 100% healthy.

“Keeping him out that extra few days helped,” Richardson said. “He’s busting to have a big game.”

Kane entered the game against the Kings with three points since returning but has impressed Richardson in other ways. Richardson mentioned Kane’s backchecking and talked about a play Thursday night in Philadelphia in which Kane dumped the puck in, allowing teammate Tyler Johnson to retrieve it.

Such plays are subtle, but they stand out to Richardson.

“That’s something that’s not in his DNA, but he knows how to win,” Richardson said. “To get him playing that way and sacrificing, going after those extra points or offensive chances, is a smart thing for us as a team, and we’re lucky that he understands that and plays [for] the team and [what] we need to win.”

Lafferty’s impact

One reason for the Hawks’ recent uptick has been forward Sam Lafferty. Richardson singled him out as an example and praised him for his feistiness Saturday in St. Louis.

“That becomes contagious on a team, not just skating but playing like a team, playing together after whistles, everybody’s in the scrums and maybe dictating a little bit of that physical play, too,” Richardson said. “I saw him take a few runs at their defensemen, and he’s a big guy that can skate. It makes you feel a little uneasy back there when a guy like that’s coming. He’s quiet; he doesn’t get into verbal battles with guys on the ice. He’s just all business, and I like everything about his game right now.”

Forward Max Domi hit similar notes after the 5-3 victory against the Blues.

“Lafferty brings something,’’ Domi said. ‘‘He’s usually our staple of skating, and he’s one of the fastest guys on our team. When he’s playing with energy, it usually infects our whole group.”

Staying connected

Even with today’s modern technology, it seems like we’re more disconnected than ever.

That isn’t the case with the Hawks.

“Nowadays in hockey or anything in the world, young people have social media, they have their iPhones and their iPads and their headphones, and they don’t seem to be connected together,” said Richardson, who was asked what has surprised him during his first season as a head coach. “They may come do their jobs together or come do what they have to do.

“This team seems like it’s an old-school hockey team. They like being together, they enjoy each other, they plan extra things with each other and I haven’t seen that on teams in a long time. That’s really not surprising, just pleasing for a coach.”
