How soon we forget!

And I wonder why you use "over 30 games in a season" when Cloonan has only played in 29 to date. But in answer to your question, since the start of Hockey East 2 forwards who have played over 30 games in a season had 0 goals and one who played 30 games had 0 goals:
Player, Season, GP, Points
Scott Perry, 1999-00, 41, 0-3-3
Brian McGuirk, 2004-05, 33, 0-1-1 - note: he scored in the U-18 exhibition game
Ryan Santana, 2009-10, 30, 0-1-1
I looked and he has not scored a goal in 61 games played, good for ninth among all players since the start of Hockey East and second among forwards.
