How many of Henry's NHL games are post lockout? And how many of those post lockout games were on defence, as opposed to being used as a fourth line forward there to play a few minutes and fight? The answer of course is 0. He's had 0 NHL games on defence since the lockout. There is a reason for that, despite his experience on a very poor expansion team pre-lockout.
As for size, yes we lack it and yes we need it... there is no disputing that in the current defence configuration... but I don't think putting in a guy who quite simply is not an NHL player is the answer to this question.
Alex Henry quite simply doesn't compare to Shane O'Brien, Woywitka, Staubitz, etc.... His game is at a level far below those guys. He's quite simply a liability on defence in the AHL... How we expect him to play 12 minutes in the NHL, I have no idea.
Never mind the fact that you are advocating for going huge minutes to Gorges and Subban, on a night where we face a back to back (with travel)... where we play 3 games in 4 nights... and 4 games in 6 nights this week, and they already played huge minutes on Monday due to being down to 5 D, and having an OT game.
This quite simply just doesn't make sense.
