BOSTON (CBS) – We all know Dave Goucher as the voice of the Boston Bruins.

But with no ice on the floor at the Garden, there isn’t much hockey to talk. So Goucher set his sights on the struggling Boston Celtics on Monday.

Listen in as Gouch vents about the Celtics’ lackadaisical efforts this season, employing his JFK impression to send a message to Danny Ainge!
