When the teams collide Tuesday at Scottrade Center, it will be the first of two meetings spanning three days. They will match up again Thursday at Staples Center.
And after facing one another twice in the past three years in the Stanley Cup Playoffs, both teams have gotten to know the other quite well.
Since the Blues (20-8-2) swept the Kings (15-10-6) and won all four regular season meetings in 2010-11, St. Louis has gone 2-7-2 against L.A. in four seasons, including a 1-0 shootout loss in L.A. on Oct. 16.
"They've got our number," Blues coach Ken Hitchcock said of the Kings. "As small as the gap's been, they've been better, and it's our job to play catch-up. Everybody knows even as well as we've played, the first time we played them in L.A. early in the season, we still didn't score a goal. Those are things we've got to address and have an honest conversation. Every time we play them, they're good hockey games. They're really well-played. They feel like playoff games. I think the players' heightened sense of urgency on both sides is there. Quite frankly, they're fun to play in and they're fun to coach in. You get such a true assessment on your own personnel.
"I think this is more about energy. What's their energy going to be like the last game of a road trip (L.A. is 1-2-1 on a five-game trip)? Are they going to be enthused and put in (the effort)? What's our energy going to be like knowing we go on the road right after? I think this game's all about energy."
