Not quite, One team played in a division with 2 other contenders, one team played in a division that featured the worst teams in the playoffs. Seeing that they were swept in back to back years against non pacific teams is pretty telling.
In the last 5 years (missed the playoffs twice) Edmonton has won exactly 1 playoff game against a non-Pacific team. It's quite obvious to everyone outside of Edmonton what's happening lol, even without looking at the stats. Not all divisions are made the same, Edmonton is the best team in the Pacific but they don't even compare to the playoff teams outside the Pacific.
1W vs 11L against teams not in the Pacific in the playoffs in the last 5 years, do what you will with that.
