Yes, a guy with 18 professional games was going to be critical to keeping this defense from crumbling. This team's defense sucked with Nemeth, and it sucks without him.
I don't expect this to be a popular opinion, because no matter where I end up, Stars fans unanimously seem to think Nemeth was a big part of this team, but I think it's because his performances are considered against lesser expectations. He looked good last season because he didn't look out of place on a bad d-core. Which says what about the d-core? Exactly.
Keep in mind, I wanted to see Nemeth get more games and I liked him on that 3rd pair with Connauton. But I think his effectiveness is overstated simply because fans overstate the value of being a defensive defenseman in today's NHL. Just check out
his possession stats.
They're not good. And if he was such a defensive defenseman, then why did he get 63% of his starts in the offensive zone? To note, his OZ zone finish was 44%. It's a classic base rate fallacy problem: he could sort of clear the crease, but that's
all he could do. This team doesn't need a defensive defenseman. It needs a good defenseman, period. Nemeth might have developed into that, but I want to see more of him (he had a horrible preseason too) before declaring his worth because I think it's reasonable to be skeptical.
