It is a combination of poor goaltending, poor PK, and injuries.
Myers has played 11 games this year and enstrom has been out twice and Trouba held out and Little was out for a fair stretch. Also, we started off the year setting a record of 32 games in 60 days.
If I had to say one thing, we don't have a goalie that is playing like a starter. Chevy needs to pick up a LHD and a vet goalie this summer.
Actually, Scheif's stats are considerably worse when not playing with Laine and while Laine's are worse without Scheifele, they are not that much worse. He is 6' 5" or something so I expect he will put on another 12-15 pounds in the next 3-4 years. He will start winning the battles against the wall that he is losing pretty easily.
