Dal Colle has the tools to be a great offensive contributor who can put up his fair share of points. He has great hockey sense and a sniper’s touch, using a great release to beat goalies from all areas of the offensive zone. Dal Colle is a big player with good reach and puck protecting abilities.
Dal Colle attended his second training camp with the Islanders after winning a Memorial Cup last year with Oshawa. Back in the OHL for his fourth season, the 19-year-old began the year with Oshawa as the team's captain.

He has been on a tear with the Frontenacs as the team has dominated the East Division. Dal Colle continues to develop his game and hone his positional play. His size and skill set suggest he can be a big part of the Islanders' future.
