A Boston, Massachussetts native, Matt Marshall has spent his formative prep school years in hockey playing for the Noble and Greenough School. A slow developer, Marshall was passed over in his draft year in 2005-2006 but rose through the ranks for the 2007 NHL Entry Draft with a season that saw him score 14 goals and 24 points in 27 games with Nobles, despite playing out of position at center, to go with 8 penalty minutes. Marshall was selected in the 8th round, 78th overall, of the 2007 USHL Entry Draft by the Waterloo Black Hawks and he finished the year ranked 63rd among all North American skaters by the NHL Central Scouting Service. The Lightning selected Marshall in the 5th Round, 150th overall of the 2007 NHL Entry Draft.
In 2007-2008, Marshall broke out offensively, particularly in the second half of the year, and finished his senior year at Nobles with 25 goals and 26 assists for 51 points in 29 games.
He is committed to play his college hockey for Vermont of the Hockey East conference.
Early indications are that Marshall will play one more year of prep school hockey with Nobles before moving on to Vermont so it could be up to five years before the Lightning see the speedy winger start his pro career.
