The Islanders host the San Jose Sharks at Barclays Center on Saturday (7 p.m. ET; MSG+, NBCSCA, NHL.TV).
"He wants to be a star," Weight said of Barzal. "He wants to be better. He was crushed when he left last year. I just felt that he was going to be able to make a step. Still has to learn. Some big centerman in the League, but he's taken some big steps."
To understand how far Barzal has come, you have to go back to this time last year, when he was an NHL player, but barely.
Barzal made the Islanders out of training camp last season. But he played in two of their first 13 games before he was returned to his junior team, Seattle of the Western Hockey League.
It wasn't easy for him to go back, not after getting a taste of NHL life. He was frustrated.
Barzal said the hardest part was feeling he was a step behind the many peers from his draft class who stayed in the NHL as rookies last season, including Ivan Provorov, Zach Werenski, Mikko Rantanen, Travis Konecny, Sebastian Aho, Brandon Carlo and Islanders teammate Anthony Beauvillier.
He could have gone back to Seattle angry, feeling he was too good for the WHL, especially after scoring 88 points in 58 games in the 2015-16 season and then actually making an NHL roster. Instead, he chose to be a pro and go back to grind, perform, produce, lead and win.
He put up 79 points, including 69 assists, in 41 games, then had 25 points in 16 playoff games to help Seattle win the Ed Chynoweth Cup as WHL champions. Barzal was named the most valuable player of the WHL finals.
