Rask isn't great, yet. The Leafs have lost Lupul for an extended period of time.
But, yes, we will need goals from every line, and every defensive pairing. Think of it, though, we had 3 rookies on D (too lazy to look up actual games played but they are rookies in my opinion), two more in the top-six (Zibanejad may have started on the 4th line against Washington but he was playing top-six minutes), and a ref who appeared to have it in for us (can the NHL fine radio announcers for abuse of on-ice officials?) Against a team described as "hot" coming in. Sure, they played their backup, and he struggled, at times, but even with all those power plays the Habs managed 1 goal.
