Housley said the team had a discussion about execution and mental preparation prior to practice, which is an area that plagued them in Chicago. The Sabres were outshot 51-28 and fed the Blackhawks' rush game with turnovers in the neutral zone.
What allowed the Sabres to maintain a 2-1 lead late in spite of the lopsided shot totals was their work ethic, along with a strong performance from goalie Robin Lehner. The Sabres were physical both along the walls and in front of their own net, and managed to block 31 shots.
With effort and emotion in check, execution stood out as the area of focus on Saturday.
"I thought we did a really good job executing and just played fast out there today," alternate captain Kyle Okposo said. "We just skated. We skated really well and moved our feet. I think we did the right things out there. It was a lot of fun, that's how we've got to play. We've just got to move and work.
"I went up to a couple guys after and just told them that practice was really good, so we've got to bring some of that energy tomorrow."
The Sabres will have to work hard and work smart against the Blues, who matched Tampa Bay for the NHL lead with 42 points following a 6-1 win over Detroit on Saturday. Forward Jaden Schwartz, who is tied for eighth in the NHL with 35 points (14+21) this season, left that game after taking a shot off his ankle.
Even without Schwartz, the Blues still boast a lineup that includes Brayden Schenn (36 points this season) and Vladimir Tarasenko at forward as well as Norris Trophy contender Alex Pietrangelo on the back end.
In other words, it will be a tall task for the Sabres, and one they've chosen to embrace.
"It's a successful trip if you get five out of six points," Okposo said. "We've got one game to go and we've got a St. Louis team that we're really focusing on. If we get the five out of six points then we're going to have to do a lot of good things and we're probably going to have to play a really good hockey game."
