Think PC unfortunately kept the overachievers from last year and sent out the under-achievers. I also believe that the flu has hit this team really hard which is part of what's going on.
I think he expected pool-party to step into a top 6 role easily. Basically everything worked out for him last year and nothing is this year. I suspect we see regression to the median towards the end of the year. Hopefully it is enough to help with our bad start.
PS - cut off for the playoffs in the West was 88 point last year. Basically a +6 win/regulation loss record. Probably will be closer this year. Basically means assuming the same weak play in the West the Oilers would have to win 10 more games then they lose... Chances are playoffs will be closer to the 90-93 point range. Meaning the Oilers would have to win 15 more games then they lose over the next 58 games. A record of say 33-18-7 would do it.
