To be honest, I think if you replaced almost any bottom teams goalie with Price and top d-man with S. Weber, even if their d-man is > Weber, it would make them at least a playoff team, potentially a contender.
Whether or not that teams current best d-man is better than Weber, Price is a franchise goalie, probably the most elite in the league currently. When you add a guy like Weber who brings a lot of elements defensively with a booming slapper for the PP, naturally it will improve pretty much any team to the point of playoff contention.
Price can steal games, and with Weber in front of him half the game it only makes it even harder to score on him. I loved having Subban, but even the biggest detractor of that trade simply cannot deny that having Weber in front of Price for 30 mins a game vs Subban makes it a lot easier for Price to steal games.
So as long as those two players are healthy, I think we will make the playoffs. So long as those two players are healthy and our better offensive forwards remain healthy too, I think we can contend for the cup. Of course it's early in the season but even if we weren't 8-0-1 and were instead 4-4-1 I do believe the games would've been really tight losses, like 2-1, 3-2 etc and Price/Montoya would still be doing okay statistically, because of having a rock in Shea Weber in front of them.
Weber out west was solid but he played against a ton of big teams night after night not very many of which were soft. On the east, he plays against a lot of soft forwards. I've seen time and time again already in this short season forwards shying away from going after pucks in corners or the front of the net simply because of his presence, where in contrast time and time again players would fight those battles against Subban.
If you gave Arizona Price instead of their #1 goalie and Weber even instead of OEL, I think they're a playoff team this season.
