I mean, sure, but Scheifele isn't some lunch-bucket scrub sent out to kneecap the Great 97 every time he steps on the ice. He's a legit PPG centre himself with an excellent playoff track record and the size, skill and speed to play strong D when he has to. And Lowry, Copp, Perrault, Morrissey, DeMeloand Pionk are no fun to play against if the Jets are able to match.
McDavid is a great player, and Drai is a very, very good one. But narratives that cast the Oilers as Cup champs in waiting, and the Jets as plucky journeyman with an impossible dream fail to note that these underdogs have an elite forward corps and some very strong 2-way players. There isn't really a walkover matchup for McDrai with the possible exception of the Jets kinda-sorta first line, but even that line has two top-end scorers in Connor and Scheifele, while McDavid is barely-average on D and Drai rarely seems interested in playing D so far as I can tell.
Not sure McDrai can be blamed for not carrying the Oilers to an easy series win. But it's hard to see which team they were going to roll over with this lineup and pressure, IMO, no matter how well they played as a 1- or 2-man unit.
