Development Coach on Cooper and Ace Flagg’s Influence

Matt MacKenzie, the development coach for the Flagg brothers and a physical and mental basketball skills trainer, spoke to Bangor Daily News about the influence the Flagg twins have on Maine High School basketball players.

MacKenzie emphasized on the Flagg twins being great role models with the kind of training they do:

“I think that when young athletes can walk in here and see Cooper and Ace going through in a full sweat in the summertime four, five days a week, they’re just a great model for what treating your body and treating yourself like a pro needs to look like,” he said.

“It certainly helps, it helps having players like that in my corner to use as an example when talking about, this is how you need to prepare.”

Ace Flagg is the only player signed by the Maine Black Bears from the 2025 Class.
