Following Thursday night’s 4-1 win over the Islanders, Rangers rookie J.T. Miller went out to eat with his family on Seventh Avenue, just a few blocks from where the 19-year-old ignited Madison Square Garden in his home debut.

He may not be recognized yet in a city of millions, but after scoring two goals in the second game of his NHL career, the 2011 first-round pick quickly ensured the Lightning will be looking out for No. 47 in tomorrow’s game at the Garden.

“It’s been crazy the last couple of weeks here, so I’m just trying to make sure I’m relaxed and I regroup again and stay on an even keel and not worry about the last game and just go into the next game like it’s my first game,” Miller said after yesterday’s practice.

Miller provided an immediate, and necessary, offensive boost beyond the Rangers’ top line, becoming the first Ranger to score multiple goals in his MSG debut since Chris Kontos in 1983. In addition to becoming the youngest Ranger to score multiple goals since Alex Kovalev in 1992, Miller’s second goal, which put the Rangers up 3-1 in the second period, was a spectacular sight for a power play that only had scored on three of 36 chances previously.

The latest in a line of Rangers rookies to have an instant impact, following Carl Hagelin and Chris Kreider last season, Miller said he’s watching the players who recently have gone through what he currently is to help ease his transition.
