Oh Captain My Captain. Anyone whose seen Dead Poet’s Society knows this quote. It’s always been one of my favorites. Robin Williams’ character Mr. Keating told his class to be daring. He may as well have been talking to Ryan Callahan. The Ranger captain delivered again. His shootout winner in Round Four allowed the Rangers to escape Boston with a 4-3 win.

“It’s a dirty road win,” Captain Cally told John Giannone after our own gritty reporter interviewed him. “We still have some things to work on. … The character this team has. I knew we’d respond.”

It’s that kind of never say die attitude from the unquestioned leader of the Blueshirts that makes him a hit with everyone. Is it any wonder that since he and blood brother Dan Girardi returned, they’ve won three in a row? As I noted during the game, this is a much different team when they play. Thankfully, neither injury kept either out long.

The Rangers blew a three-goal lead in the third period. Astonishingly, the Bruins scored twice with Tuukka Rask on the bench for an extra attacker. Despite trailing by three, they never gave up. The mark of a good team. David Krejci started the comeback by tucking a rebound under Henrik Lundqvist. Up till that point, Lundqvist had been sensational. It looked like he was zeroing in on his first shutout. Instead, Nathan Horton and Brad Marchand scored 48 seconds apart, sending TD Garden into bedlam.

It was mind boggling to find our team in a tie game after Anton Stralman had put them up 3-0 with under 18 minutes left in regulation. But that’s exactly what happened. Rick Nash, who was dominant throughout including a ridiculous goal in Round Two of the shootout- took a hooking penalty on Milan Lucic. He absorbed a cheap hit from Lucic and went back at him. Our PK had been back on track. This time, they didn’t get it done with ironically Lucic setting up Krejci’s power play goal.

For much of the third, the Rangers protected the lead. Maybe it was the ridiculous praise of Sam Rosen and Joe Micheletti. Before you knew it, they’d blown another lead to the Bruins, who also rallied to tie up the last meeting on 1/23 before Marian Gaborik won it in overtime to complete a hat trick. One thing about Boston. They’re never out of a game. They figured out a way to rally again. Perhaps John Tortorella might want to tell his team to not get passive.

The four-on-four overtime was spectacular. Both teams had chances to win it but were turned away. In particular, the Rangers came close at the end but Rask made a save at the buzzer.

In the shootout, Lundqvist got a glove on Tyler Seguin’s wrist shot. Rask denied Gaborik, who tried to go five-hole. After Lundqvist closed up the five-hole on Patrice Bergeron, Nash faked out Rask by tucking a forehand to put the Rangers up 1-0 after two rounds. But Hank couldn’t stop that annoying pest Marchand, who again tied it as he had at 19:17 of regulation. With a chance to win it, Brad Richards was rejected by Rask. He had a miserable night. Gaborik wasn’t much better.

In Round Four, Claude Julien sent out Krejci. He tried to outthink Lundqvist but he stayed right with him to stuff a backhand attempt. Tortorella stuck with his guns, sending out Callahan. Instead of going to his bread and butter forehand deke, he went upstairs on Rask to clinch it for the Rangers. It was the first game that went to a shootout for our team. Good thing we had Captain Cally.

Carl Hagelin got the scoring started when he took advantage of a power move by Nash to steer home his fourth in five games. The play was started by Girardi, who caught the Bruins in a change. He found Nash, who flew to the net and while being taken down, somehow managed to pass the puck to Hagelin for his goal. A tremendous play by Nash, who’s starting to flex his muscles. Hagelin and Derek Stepan are the right fit.

Stepan played another strong game, winning some key draws late against one of the best faceoff teams. He was over .500 (9-and-8) again. Of course, the Bruins won 37 of 54. But Stepan kept his focus. He also scored his second of the season. Off a neutral zone turnover, he whistled a laser past Rask for a 2-0 margin. He could’ve had another if not for Rask denying him. Stepan is playing with more purpose, even forcing Zdeno Chara to jab him out of the crease.

Following another colossal five-on-three epic fail, Stralman got his first unassisted. At 3-0, the game should’ve been over. Instead, Boston had other ideas. The important thing is the Rangers won. They’ll take a three-game win streak into a Garden rematch against the slumping Islanders Thursday.

BONY 3 Stars:

3rd Star-Rick Nash, NYR (set up Hagelin, wicked shootout goal)
2nd Star-Henrik Lundqvist, NYR (37 saves, including some crucial ones early)
1st Star-Derek Stepan, NYR (2nd of season, 9-for-17 on draws, more confident)

Notes: Jeff Halpern had a strong night in the faceoff circle, winning nine of 11. He’s really making a difference on the fourth line with Darroll Powe, who outside of a delay of game minor was solid. They’ve meshed well with Arron Asham, who wisely stayed away from a fight with Shawn Thornton. … Real big of Marchand to mix it up with Gaborik post scrum. What a guy. … Rangers blocked 25 shots to Boston’s 9. Girardi and Ryan McDonagh each had seven.

… Since Tortorella took him off the power play, Mike Del Zotto has bounced back with two better efforts. Less is more for MDZ. … Matt Gilroy is playing more confidently but Tortorella refuses to use him in the third. … The Rangers took another bench minor. That’s six. Outside of that, they’ve been more disciplined. … Lucic had two assists and Dennis Seidenberg did as well for the Bruins. … Bergeron (14-and-4) on faceoffs. Dominant. … Rask turned aside 26 of 29.
