Contrary to what Hosh stated, I personally think the Flames need to win the rest of the games.
First of all, I think the Flames need to have a good momentum going into the playoffs. I think the Flames need to end the season on a strong note and by doing so they will carry it forward to the playoffs with a sense of confidence.
Secondly, by winning the rest of the games they will have more trust on the lines they have and will decrease the likelihood of any significant shake up of the lines. This will maintain any chemistry that's developing currently that will only work in the Flames' favour.
I really should listen in class so I will leave it at that.
