Strongly disagree with this, at least that they did this with any sort of consistency last season. I agree that getting "tougher" in a classic sense should not be a priority - though if it comes with an otherwise good player, it is a bonus. I do however think that the NYR need to diversify their lineup and get "tougher to play against" specifically by developing the ability to play a grinding game when called upon. Tampa for example can absolutely do that, it's what makes them so hard to beat.
That dimension is IMO what the 2021 NYR were really lacking and gets exposed in certain types of games and/or against certain types of opponents. Can that improve with a coaching change? I think and hope so. But I think there is a need to switch up some skill sets as well.
