Mike Sullivan is a God

Under Mike Johnston this season, the Penguins were playing middling, low-event, boring hockey. It was painful to watch some nights. Things have changed.

Since Mike Johnston's firing and Mike Sullivan's subsequent promotion to head coach of the Penguins, things have looked up VERY much so. The Penguins are fun to watch again, and nearly every player has seen a significant bump in their production, as far as possession metrics go.

This chart does not include the data from the recent game against the Islanders, where there differential dipped a bit, but still, it's easy to see the differences here.
