Well, we have a very different definition of grit then. Questioning Marner's grit doesn't question Marner's value. In fact the conclusion of my reply ended in noting our strength, that icing our full top six presents difficulties of a different sort (i.e. with skill) to clubs.
You describe the problem without providing a suggestion of solution from available personnel. And as far as describing Hyman to be useless, that's preference against fact. Hyman is a serviceable player and does provide value as a bottom piece. And the strategy isn't to insert a plugger at the expense of a better player. When Babcock coaches the national team (which he most certainly has some say as to it's selection of personnel) does he insist that a comparable to Zach Hyman be selected for Team Canada? Of course not. His access to resources changes.
Given that we have Nylander out and Matthews out, that measurably alters the effect he can impose as a coach with a top six that includes Matthews, Tavares, Marner, Nylander, Kapanen and Marleau. If Babcock can ice a first line of Kapanen-Matthews-Nylander, it doesn't matter if Boston starts or doesn't start a game with Pastrnak-Bergeron-Marchand because the second line is Marleau-Tavares-Marner. But when Nylander and Matthews aren't available, the rest of the club shoulders the burden, as unappealing as that sounds to have Freddie Gauthier, Josh Leivo and Zach Hyman shoulder that difference.
Swapping out Pastrnak for Hyman as an indicator for Babcock's decisions?
How about we reserve judgement until Toronto ices it's full squad against Boston's and then determine whether Babcock's game in game out decisions haven't achieved their purpose? Namely to improve our club in a measurable fashion, season over season. And has Babcock achieved that? Yep. The snapshots might not all be award winners, but the album is looking better and better the longer he's the coach of the Toronto Maple Leafs.
