They're not.
Zona is in that weird place that rebuilding teams find themselves in, waiting to see if a bucket of high skill young kids are going to figure it out (Strome, Perlini, Chychrun, Dvorak, Crouse, Merkley, Capobianco) but they don't have a terrible looking group to slot those kids in around either
Keller, OEL, AG, Stepan, Hjalmarsson, Goligoski, Demers. Raanta has quietly established himself as a legit 1A imo. Like I argued over on the Habs board, they've got something going on there that just hasn't shown up in the points column yet. Their offence was disgustingly bad last season, but if a couple of those kids sort themselves out and make steps forward (nevermind if it's Strome, who was PPG+ in the AHL as a 20 yr old), they become respectable in a hurry. Not good yet, but chasing the playoff bubble absolutely.
The Habs are a mess. Nothing up the middle of their forward group, slow on the blueline, with what appears to be a half broken former superstar in net. Now, if Price bounces back to even .920ish level, that would be a huge help and the Habs probably creep into average territory defensively. (They were 26th last season and while the goaltending wasn't good overall, at .907 it wasn't exactly tragic either) But even if that happens, I don't see a scenario in which the Habs are markedly better offensively. Even if Weber plays the entire season, and MaxPac isn't traded and bounces back to normal. Even if Hudon and Lehkonen take steps forward and Byron keeps up this mid/late career surge, I just don't see how this group becomes even average offensively. Drouin-Domi (I'm assuming this is what's going to happen)-Danault are 2 wingers and a solid 3C up the middle. It's just not going to end well for them.
So yeah, even if everything goes right for this group they might, might be a 90 point team with their best players either older and starting to break down or with a foot halfway out the door.
