Hot take, d-men are a pretty overrated position. While a downgrade on the center position tends to have a huge impact on on-ice results, that's not really the case with d-men. With Rielly out, we lose:
- His ES performance (where he's basically Two-Face)
- His PP impact (which can adequately be replaced by Sandin)
- His PK impact (he shouldn't even play, and Marincin is probably better)
Given that our ES performance hasn't even been hurt that bad in his absence, his injury has had surprisingly little effect. Especially given the compounding effect of having Muzzin out too.
Matthews and Tavares not only play the more important position, they are also vastly superior players. This is a no contest. I honestly think we'd be hit harder without Marner and Nylander too, given the synergy effect of our top four forwards.
On that note, I wouldn't mind if we built a defense consisting of six d-men who play a low-key, reliable game with a solid outlet game. Should be relatively cheap and effective.
