Analytically, Skjei - Pesce has suffered a drop off, but not a huge one; per MoneyPuck, the two are at 53.7% xGF% compared to ~57% over the preceding three seasons.
A SAH defender is useful, with Orlov so aggressive in this system. Chatfield works as his partner now, but will that hold if that duo is tasked with Top 4 shutdown minutes?
Savard actually makes some sense, if the FO wanted to get ahead of things. Tanev and DeMelo are on track to be available in July, but that could easily change. However, if Pesce is valued by the league similarly, there's little point in moving on for both sides.
