I’m hoping to get some advice on proposing a trade. The team I’m looking to propose a trade to is stacked at Center but light on D. Here’s his roster at those positions:

Centers
McDavid
Draisaitl
Petterson
Marner
Malkin
Sharangovich
Zergas

Defense
Byram
Dahlin
Grezleck

You can see he doesn’t even have enough to roster a full D lineup. I’m wondering it's worth proposing Rielly or Josi for Petterson or Marner (maybe Josi for Draisaitl, but that feels like it might be a reach)? For the D I'd be giving up, does that seem like good value in return?
