Anything is possible, but considering how the series has evolved through the first 4 games, it's highly unlikely. Carolina is just playing too well to imagine the Oilers going on a sweep and winning 3 straight-including 2 in Carolina. In addition, the Oiler powerplay has been practically non-existant, only converting for 1 goal through the games played so far. Conversely, the Canes powerplay is very effective. Oilers cannot skate with the Canes, and the Canes have much more scoring depth.
The Oilers goaltending cannot be blamed, but when you only score 3 goals over a 3 game stretch (games 2-4), they have to be considering themselves fortunate they are even still alive! Ward in net for Carolina looks like the odds on favorite to win the CS Award, and deservedly so.
Sorry Oiler fans, the gig is up, the Canes will finish off Edmonton tomorrow night.
