The Blackhawks overcame a slow start as a two-goal hole was erased early in the middle frame with Kirby Dach and MacKenzie Entwistle scoring in the opening six minutes of the period to make it 2-2.
But a sequence of penalties -- five total in a 17-minute span from the middle of the second period into the early third -- throttled the visitors' new-found momentum and led to a 5-2 Arizona lead just four minutes into the final frame, with two of the three goals on the man advantage.
It was a similar scenario on Sunday night against Calgary, with the Flames taking advantage of three straight penalties in a 1-1 game en route to a 5-1 win.
"Our start was pretty flat. In the second, we got into penalty trouble again," Toews said. "Moments like that -- giving up one, two, three goals and we get ourselves in a hole -- those are making the difference for us right now and something we've got to nip in the bud, try and see when those lapses are coming and keep each other engaged on the bench and find ways to say the right things and keep playing with energy, especially when teams are coming back at us."
"We need to play with pride," Connor Murphy added. "We all care about the end result of the game, but that's only going to take care of itself if you do put in that effort every shift and give yourself and your team the best chance to come out with a win by doing that every shift. There's a lot of good teams in this league that play consistent and if we take any time off, like we did tonight and in some of these games, they're going to end up getting grade-A chances and scoring and then we're going to be trying to catch up like we did tonight."
A pair of goals from Toews and Alex DeBrincat late in the third made things interesting late, but the three goal hole was too much to overcome for the second time in the game. Arizona added a late empty-netter to seal the final, 6-4.
"We had a lot of chances and we were able to put some pressure on them right to the end there even though we were down three goals," Toews said. "There's times we're playing good hockey, we've just got to find a way to be more consistent."
"We have great players and that's something we talk about with each other," Murphy added. "That's what's probably most frustrating, that we haven't been able to show that for each other."
