Those '96 BA teams were stacked 6-7 years ago. Someone post a roster. From Hannifin to Donato to Gaudette and about 25 other notable kids.
You might be thinking of the '96 Boston Mission team, and attributing it to BA. You can see the BA U16 and U18 rosters on EliteProspects.com
Adam Gaudette played a handful of games for the U16 BA team in 11/12 and 12/13, but really didn't burst onto the scene until 13/14 at Thayer.
Hanifin "grew up" on SSK, playing with Colin White and some others that went D1. He played a handful of games for BA in 11/12, but on the U18 team. He was already in Plymouth by the 13/14 season.
I don't think Gaudette was on the infamous Mission team, and Hanifin was only briefly. That team is a bit of a unicorn, as the list of players that are said to have played on it has grown over the years.
