Don't want to derail the GDT, but it's not even that he just a couple poor seasons. The guy can't string together one solid month. Hell even a guy like MacDonald can have a decent month of stats (or fluky season!).
You can say all you want about Corsi, but he
hasn't had one single month, in his 12 month NHL career, close to break-even. You can't even even blame partners. He's played a bunch with one of the first lines in hockey thanks to whatshisface, and has played extensive minutes with every defenseman on this team with the exception of Sanheim, and has flopped with every single one of them.
His -6.09 CF% rel over the last two seasons ranks 93 out of 94 defensemen with as many minutes. His -4.76 xGF% rel also ranks 93rd out of 94 defensemen over that time, so he is equally as bad when adjusting for quality. Quite simply, the guy is a plug. Fletch should do what Hextall didn't- sell high.
The PDO trend is interesting. Not because it is predictive, but because two years in a row it was high in the first half of the year and dipped in the second half. Perfect for a coach that values and hangs onto unsustainable, early season, goal results above everything else.
