When Jack Capuano gets excited, he talks very fast, with little time to pause for sentences or breath.

Kind of like Wednesday morning at the Coliseum, when the Islanders coach spoke emphatically about a coming season ripe with lofty goals and historical significance.

“The expectations are having the mindset to go in and win every single hockey game,” Capuano told The Post before his team’s 4-2 preseason loss to the Hurricanes, during which his penalty kill carried over its struggles from last season and gave up three power-play goals. “The expectations are to go in there and make sure we’re extremely tough to play against — that we’re a postseason team.

“Why didn’t we make the postseason last year? A, B, C, and D. What’s the process and why we’re going to make it this year? A, B, C, and D. It will be laid out for all our guys.”

Capuano is in his fifth year behind the Islanders bench — his fourth full season — and he has taken his team to the postseason just once, at the end of the lockout-shortened season two years ago. There, his young and fast team made a splash, taking the No. 1-seeded Penguins to six games, but still kept the franchise’s most recent playoff series win in 1993.

Come opening night on Oct. 10 in Carolina, and the following night when the Hurricanes come up and play the last home-opener at the Coliseum, the pressure will be on. Since the Islanders’ inaugural season of 1972, they have called this creaky old barn on Hempstead Turnpike home, and yet come this time next season, that home will be in Brooklyn, at Barclays Center, where they play an exhibition game against the Devils on Friday night.

In the interim, Capuano is cognizant of the fact there are fans on Long Island not willing to make a trip into Atlantic Terminal, and this team, under his guidance and fueled by his motivation, is going to be the one to send this place off.
