St.Louis is 22-3-4 at home this season but only 8-11-3 on the road. At home they score a average of 2.83 GPG but only 1.95 on the road making them the lowest scoring road team in the NHL. In fact, St.Louis has only gone over 5.5 goals on-the-road 4 times this season (all 4 times were in Oct; all 4 games were 4-2 scores; one of those an empty net).
Tonight Brian Elliot will face his former team. So far in Feb he has a GAA of 1.62 in 3 starts to improve his season GAA to 1.69 and SV% to 0.938.

Ottawa has been struggling lately going only 3-6-1 in their last 10. They have lost their last 3 at home and have scored only 1 goal in those 3 games.
Since the beginning of January the Senators have played 16 games and have finished under 5.5 goals in 13 of those games.
Anderson is the confirmed starter for tonight. In January he had a GAA of 2.24 and SV% of 0.933.

Ottawa needs to end a 6 game losing streak which has dropped them to the 8th playoff position so they should play a careful game tonight.

I think everything in this games points to a low score.

Prediction: 2-1 for Ottawa
