I voted Oilers in 6.
Reasons, hm...well, first they have McDrai combo. I think they both elevated their two way game, they are overall better PO players now...not by a big margin, but compared to the last year, in some extent yes.
Oilers depth is good. Panthers have better depth overall, but I think Oilers depth is good enough for this run...and I dont think they need better depth than Panthers....they have McDrai + Bouchard + RNH...thats the foundation, considering amount of points (offense) those four generate, they dont need better depth than Panthers.
Defense-I think they are evenly matched. no favorites here.
Goal-Panthers in better position, but Skinner looks in good spirits, dont expect from him +.930 SCF stats, but I think he could hover around .910 which is good enough IMO.
At the end special teams, Oilers are better.
That is going to decide this series. Oilers offense in general (their 5vs5 game has been great so far) + special teams.
