The bottom six won't be able to hold serve if Sullivan keeps asking so much out of them defensively. With our top 6 so inept defensively, and unable to handle tough assignments, it creates an unrealistic expectation that our bottom six should not only deal with the toughest assignments defensively, but also score. Carter and Granlund would not have been as terrible down the stretch last year if they got some easier assignments.
Top to bottom, winning teams not only play a better structured game, but they have top 6 players who actually defend. Look at what Mark Stone has done in Vegas, not to mention Karlsson, Stephenson, even Eichel has played well defensively for them.
But with the reality being Sullivan is going to use his bottom 6 like checkers, then we'll need to overpay for guys like Kampf who can actually handle it. And most importantly, they can't have a roster full of older, slowing, defensive black holes like Granlund, Rust, and Carter they try to use as checkers.
People keep advocating for Rust on L3, and if we had a time machine and could put 2017 Rust on it, that would be fine. But that player doesn't exist anymore.
