Cole Eiserman is bigger, faster and more versatile than he was when the Islanders drafted him with the 20th overall pick last year.

And after a strong freshman season at Boston University, there was speculation the powerful left wing would bring his sharpshooting skills to the Islanders by signing an entry level deal as the team looks to make its offense more consistent and dangerous.

Perhaps not.

“I think I’m going back to school,” Eiserman told Newsday. “The NHL is such a hard league to play in. The pace is so high. I just think another year of getting bigger, stronger, faster is not gonna hurt you."

Eiserman showed off his impressive shot, dazzling the fans that filled Northwell Health Ice Center in East Meadow on the second day of the team’s summer prospect development camp on Tuesday. Despite his improvement in other areas of the game, it’s likely that Eiserman returns to Boston for his sophomore season.

Eiserman’s goal-scoring ability always has been top-notch, but there were questions about his defense prior to last year’s draft.

Eiserman led BU with 25 goals in his freshman season as the Terriers reached the NCAA championship game. He totaled 36 points in 39 games. The Newburyport, Massachusetts, native had three goals and four assists in seven games for the gold medal-winning U.S. team at the World Junior Championships.

“I just learned how to play different roles,” Eiserman said. “At BU, you play one role one night and then you’re somewhere else another night. You play first line, play third line. At World Juniors, I was second line and playing with [Islanders 2023 second-round pick Danny Nelson] and the next game, I was 13th forward and had to play that role.”

The 6-foot, 200-pound lefty said he grew about an inch and put on some muscle in the last year. Eiserman, who turns 19 next month, and Matthew Schaefer, the No. 1 pick in last weekend’s draft, figure to be future faces of the franchise.

“He’s amazing. He’s a great forward and he has so much skill,” Schaefer said. “He has a bomb of a shot. I’ll see if he can teach me how to shoot the puck a little bit harder.”

Eiserman said that he sat with Schaefer when the team had dinner Sunday night. What has the 17-year-old Canadian standout learned from the Islanders’ 2024 first-round selection?

“They picked you for a reason," Schaefer said, "so you’ve just got to go out there and obviously, enjoy it, but work as hard as you can and compete, compete, compete.”
