That Leddy-Mayfield pairing makes me woof sometimes. They've played together long enough to have developed some trust/chemistry, but both are suspect handling the puck along the boards. Leddy is a great skater, but he completely lacks Toew's ability to carry the puck up the middle of the ice instead of getting funneled to the boards. Otoh a couple of good/lucky board wraps/indirect passes by that pair end up as goals for (both Palmieri goals). So they don't end the night with a big minus. Lucky.
NYI depserately need both some phsyicality down low, and movement up high to get the PP going. I doubt they do this tied or leading, but if behind they really ought to consider a 5-man forward unit with Bailey or Barzal at the top either bumping or running the PP. Maybe have a heavy group (Wahlstrom, Nelson, Palmieri) up front for puck retrieval. What they're doing isn't working - if they fail to carry it in, they never retreive a dump-in. Heck, put Cizikas (not Martin or Clutterbuck) in there if necessary.
