The Rangers’ best team has Barclay Goodrow playing fourth-line center. But because of injuries and coaching decisions, Goodrow has filled that role only once through the season’s first six games. That was for the 6-4 victory against the Ducks on Oct. 17 in which he skated between Dryden Hunt and Ryan Reaves.

And No. 21 won’t be playing there for the foreseeable future in the wake of Sunday’s suspected concussion sustained by Filip Chytil in that early first-period collision with Columbus’ Cole Sillinger. The foreseeable future encompasses at least a week and the next four games, per a club advisory.

So Goodrow, who had played five games on Chytil’s wing with four different third parties, will slide into the middle of the third line in No. 72’s absence as he did for the final 58 minutes on Sunday. Ryan Carpenter, meanwhile, will remain as the club’s fourth-line center.

Issues of depth in New York that can manifest even in the best of times will become more apparent without Chytil, who had been playing assertive, self-confident hockey. So will the lack of definition of both the Blueshirts’ third and fourth lines. So will the absence of depth down the middle throughout the organization.
