It remains to be seen whether or not defenseman Matt Grzelcyk will be medically cleared to play tomorrow night, but there's a larger question: do you even play him if he gets cleared?
On the surface, it seems like a slam dunk: yes, you play him.
He can chip in with a little offense from the blue line as well, which is never a bad thing in a winner-take-all Game 7.
Still, the Bruins should exercise caution, both for their own sake and for Grzelcyk's.
Ideally, the team wouldn't allow him to come back until they're 100% sure he's fine. But there's always the risk of another concussion, and it's not exactly cynical to think a player might try to push through lingering symptoms to play in a Game 7.
There's also the issue of rust. Tomorrow will mark two weeks since the last time Grzelcyk played in a game, no small matter in the middle of the Stanley Cup Final.
Finally, the Bruins looked pretty good onthe back-end Sunday night, throwing an element of "if it ain't broke, don't fix it" into the mix.
With the Blues probably preparing to take as many liberties as possible in Game 7, an injured defenseman could be disastrous. When you have a guy like Grzelcyk, who may be a step or two off until he gets his legs under him, or Chara, who is probably a knock away from more jaw agony, it gives you pause.
If Grzelcyk does play, there's the matter of who comes out. Logically, it'd be John Moore, who is a left shot like Grzelcyk.
You could also take out Connor Clifton, but that would force one of Moore or Grzelcyk to play on his off side.
It's a good problem to have: either you get a good defenseman back or you roll with a unit that looked solid in Game 6.
With a guy coming back from a concussion and a team that will probably be head-hunting, I'd lean toward the latter.
