They really need to close this thing out tonight or in Game 5. If Chicago is able to get it back to 3-2 via wins in Games 4 and 5, I think it really becomes all bets are off because they will have recaptured momentum and it wouldn't really matter that they were still down a game - Games 6 and 7 could easily go either way.
I keep waiting for Nashville to slip up for extended periods of time during a game or for Chicago's superior all-around skill to show itself, but the only period of time that Chicago has been in control of this series was the first half of the second period in Game 3. Toews, Kane, Panarin, and Hossa have combined for 2 points in this series.
