J.T. Miller was brought in to make a difference. At least, that was the biggest reason the Rangers went out and got him last January from the Canucks.

Instead of building on a strong finish to last season in his return to Broadway, Miller has been missing most of the first 21 games this season. He’s scored only four goals so far and has six assists for a disappointing total of 10 points.

When he was named the new captain of the Rangers before training camp, it was believed that his tenacious style would be a good fit for a bland leadership that needed a bit more personality. While he says all the right things following games, such as the frustrating loss to the Golden Knights, he isn’t backing up those words.

Even worse, it was Miller, who was a spectator on the Knights’ second goal. A stick wave as the play continued, leading to Ben Hutton beating Igor Shesterkin, made it look like he didn’t care. So much for the No More BS moniker he came up with prior to the start of the season.

It’s bad enough that he’s not playing well. With lazy plays like that one, it’s emblematic of how Miller’s failed thus far as a captain. He’s supposed to lead by example. Instead, there’s been too many instances where he isn’t noticeable during shifts.

Rangers head coach Mike Sullivan has tried everything to get Miller and a weak offense going. That’s included having Miller play with Mika Zibanejad and Artemi Panarin, who hasn’t exactly been consistent, either. But at least he’s back to putting up points since shaving his head.

Much more is expected from a no-nonsense player who averaged over point-per-game with Vancouver. Perhaps that production was boosted by playing with current Canucks captain Quinn Hughes, who even after sitting out a game with an injury, erupted for 10 assists in his last three games played.

Regardless, the 32-year-old Miller isn’t coming close to delivering on what he promised. He says he’s frustrated that he isn’t producing. So are the fans who bought into his second act at MSG.

Although they didn’t overpay to get him, in dealing away Filip Chytil, Vincent Mancini, and a first round pick, the Rangers aren’t getting much bang for their buck. He gets paid $8 million regardless. If he isn’t injured like he was during preseason, there aren’t any excuses for his lackadaisical play.

Stop talking. Start performing. How’s that for a reality check. No BS.
