I'm not going to argue that the Jackets will succeed in the playoffs or won't get swept, but get their stuff together? They're 7-1-2 in their last 10. This isn't last year when the Jackets limped in to the playoffs. Just because they're the Penguins ***** doesn't mean their stuff isn't together. If they get swept or don't win, it won't be because their stuff isn't together.
Sure, they aren't limping into the playoffs, but by "getting their stuff together" I mean they need to find a way to beat the Penguins i.e. put up a fight against them.
Since 2016 the Penguins records against the Blue Jackets is 11-3, the overall record is even worse (31-15 in favor of the Penguins). The Jackets have lost roughly 2/3 of their games against the Penguins and have only been good against the Pens for a brief period of time between late 2014 and late 2015. Outside of that it's a dumpster fire, i.e. historically bad record.
I haven't done much research into the Jackets record against other teams, maybe there are teams they do worse again but having watched a few Columbus vs. Penguins games this year and in the past I'm not too optimistic.
Don't get me wrong here, I am rooting for the Jackets all the way, but I'm not very optimistic. I hope they prove me wrong.
edit: Keep in mind I posted this before the seedings were settled. Don't think the Caps are likely to sweep them.
