Just when the Blackhawks were playing their best hockey and led the NHL in points last season, the bottom fell out with a nine-game losing skid.

Fast-forward to 2013 and the Hawks are again at the top and flying high as the only team in the league without a loss in regulation with a 9-0-2 record. The late-January to mid-February slide during the '11-12 season is a good reminder of how things can break bad in a hurry.

"It's tough to find a weakness in our game right now but we learned last year it's easy to get complacent," veteran winger Patrick Sharp said. "We know how competitive the league is. The goal in our locker room is to get better every night. We want the two points every night but playing well and improving is the main key."

There has been little room for improvement during the season-high six-game trip that ends Sunday night against the Predators in Nashville. The Hawks are currently riding a three-game winning streak and have a 3-0-2 mark during the journey.
