I agree with Miller and Luke being less expandable than Joker. But lately, he's bringing more to the table than Jurco. Not to forget that he's an essential part of the 4th line,
all season long. As Weiss isn't fitting on the 4th line, playing him shouldn't be dependent from Joker being on or off the ice.
Given that everyone would be healthy, I don't see a spot for Weiss, as the Top 9 should include Z, Dats, Abby, Gus, Helm, Tats, Cole, She and Pulkks. In case someone is injured, play Weiss instead. My beef with Babs not playing Weiss was mostly due to benching him while we've injuries. When there are none, he just has the chance to jump in, when someone ****s up and doesn't deserve a spot for the time being.
