No need to panic on the 2-1s. that can be easily cleaned. Burns will be fine, he's playing half assed and won't in the real season.
The bigger issue is individuals. The hertl line is strong. The donkey line is strong. The 4th line is kinda nothing thus far. However, the Pavs-Kane-Jumbo line has maybe one moderate chance offensively and a half dozen good chances against, including the shorthanded goal. That line, with their 18M in cap space and "1st line" title needs to be a positive. Karlsson or not, they need that line to be effective. Personally, I'd like to see jumbo and Sorensen swap spots. Get a hardworking, quick player on the first line and get Jumbo back into game shape where he cant do any damage.
