The Islanders must stop treating top power-play unit as sacred if they want to avoid another flop

One of the first lessons Lane Lambert must take into his second year as an NHL bench boss comes from the Islanders’ biggest failure of 2022-23.

That would be in building a coherent five-on-four attack after the Islanders’ 15.77 percent power-play conversion rate ranked 30th in the league over the full season and got worse as the year went on.

After a free-agency period in which the only addition to the forward group was Julien Gauthier — and he is very much not an option for power-play minutes — the five-on-four depth chart going into camp reads roughly the same as it did until Game 6 of the playoffs against the Hurricanes.

To refresh your memory, that is a first unit of Noah Dobson, Mathew Barzal, Bo Horvat, Brock Nelson and Anders Lee.
