One game does not make a rookie’s career, even if J.T. Miller’s performance was historic by Rangers stan­dards and storybook in terms of getting a first-shift goal in his Madison Square Garden debut.

Given coach John Tortorel­la’s urgency in coaxing some consistency out of the Rangers, all Miller’s two-goal outing in a 4-1 win over the Islanders on Thursday night did was guaran­tee him a spot in Sunday’s line­up against the Lightning.

With captain Ryan Callahan back after missing three games with an injured left shoulder, struggling veteran Brian Boyle a healthy scratch but soon to get another opportunity and Tor­torella admitting before the game he considered benching Marian Gaborik, among others, there is a logjam at forward for the Rangers (5-5-0).

“He has a lot of puck poise for such a young kid,” Tortorel­la said of 19-year-old Miller, the 15th overall pick in the 2011 draft. “He’s got some bite to him. I’d rather have a guy that you need to tame a little bit as he’s learning to be a pro rather than [try] to get someone to play with some spunk like that.” “He’s got some good strut to his game,” Tortorella added. “We just have to make sure he doesn’t cross the line the other way. He’s done that a few times along the way.” Gaborik also scored, snap­ping a four-game goal-less streak and Henrik Lundqvist, among those cited by Tortorel­la before the game as underper­forming, made 27 saves.

“It just gets you much sharp­er and we know we have to be better consistently,” said defenseman Marc Staal, who had two assists, of Tortorella's words and actions since Tuesday's 3-1 loss at New Jersey.
