I guess you forget the 2 game set where Trouba knocked the f*** out of one of the Bruins, Lemieux put a beating on Frederic and Lindgren hammered Pasternak?
They went 1-1 in those games, but over the course of both games they definitely got the better of the Bruins physically. They're anything but a tough and gritty team. They have elements of it, maybe even more of it than the Rangers do, but I wouldn't categorize the Rangers as tough or gritty either.
They didn't ride "toughness and grit" to beating Washington. Boston won because they were the deeper team overall and their top players showed up. They'll make pretty easy work of who ever wins the Pens-Isles series too.
On the NYR: Their issues last year really stemmed from listless play (a lot of this was on coaching) and a homogenous approach to creating offense (which was both a roster construction and a coaching thing). Our forecheck is non existent, we lost like 90% of the races to loose pucks, our board play was awful, etc. If we want to equate being "soft" with lacking in those areas then yeah, we're soft. That needs to improve.
