I wouldn't call it smashed up, I would call it under developed. Low heights start to dominate the arctic region prior to 120 so to me that is signalling the delayed but inevitable strengthening of the Polar Vortex and probably a return to a +AO. If modelling continues in the same vein then any weak ridging into Greenland will get flattened out as we head through Nov.
Model watching has been good the past week or so but I don't think there has ever been modelled a full on Greenland block and the chart posted in the quote from last year, well, we could end up back in that position by mid month imo.
