Vegas had multiple good scorers on multiple lines though ... asking Draisaitl to carry a line without much help is not a fair ask really.
He's not Evgeni Malkin.
Without McDavid on the ice we are probably one of the crappier teams in the NHL, that's just a reality. Doesn't mean it will be that way forever, in a couple of years a smart manager could turn this around very quickly once Yamamoto, Puljujarvi, Bouchard get their legs under them and you can maybe get up from under that Lucic contract and add perhaps a high end winger for Leon to create with via draft or trade.
If you can find a manager that doesn't get bent over in trades and negotiates harder on contracts, this can turn fairly quickly, we just need to get that ASAP, hopefully one year from now we have that and can get serious about building a real contender at some point.
