I think the reason that Willy appears to have slowed down lately is twofold: firstly the PP has been awful for over a month now which takes away a lot of good puck touches and points, and secondly, he's now playing third-line with Holmberg, who for as much as I like him, is not nearly good enough offensively to play with 88. He has also had some bad luck, by my eye-test could have easily come away with 3-4 assists last night. Sprung a couple of guys for a breakaway, set up people in the slot, and again did all the work on the Robertson goal but didn't get a point for it.
Seems to be that he has been working more on his defensive game and being less selfish. I liked his curl-up last night rather than trying for the EN. Also, his attitude is fantastic. Marner would have pouted about being punted to the third line, 88 says nothing, and just gets to work.
