Here's my weak attempt at decrypting this Rorschach blotch: when Ceci is on the ice there's an excess (i.e., above average) number of shots coming from the point on Ceci's side (on both sides actually), which could possibly be blamed on forwards playing too low in Boucher's system. A lot of excess shots actually come from the other side, especially right in front of the net, which could then be mostly blamed on whoever is Ceci's partner?
Still, it's crazy that for a defenseman on a "shutdown" pairing we'd see such an excess of shots from right in front of the net. Just to trigger Burrowsaurus, there could be an explanation in the quality of the competition.
But I imagine that with a better defenseman, or a better defensive system, we'd see more blue than red on his side too...
Please feel free to correct my understanding of the chart!
