Versteeg had a really good point about Rielly's passing on the PP on Leafs Hour. He compared the Leafs PP to the Lightning PP and basically said Rielly has an issue where he's too close to the left point along the boards and cramming up Marner on the wall. What you want is a bit of separation between he and Marner, so Marner can forehand it to LHD Rielly who can sweep it diagonally down towards the RW wall where a Matthews would be. That's sort of the triangle the Lightning have with Stamkos to Hedman (with the long reach) over to Kucherov. It's just the basics you see on a functional PP. Kind of confirmed my observation Rielly doesn't distribute to his right very efficiently, but the crowding of Marner along the wall was a well taken point too.
