Bill Chadwick, aka the Big Whistle, was a color man for the New York Rangers TV broadcasts during my youth. Prior to his broadcasting career, he was a longtime NHL referee, although I see by his Wikipedia page
that there was a ten-year gap between the two jobs.
Chadwick was an aggressive "homer" and in his last few years became noted for his exhortations to Rangers defenseman Barry Beck, to "Shoot the puck, Bawwy!" He had the Elmer Fudd speech defect in which all his "R"s became "W"s. This caused some amusement when the Rangers came up with a player named Mario Marois, whose name he pronounced with evident difficulty as Mawio Mawa.
I didn't particularly like Chadwick; like all old people (now including me) he tended to dwell too much on how much better things were in the past. I do find it interesting that he almost lost both his eyes while playing hockey, and that he experienced some discrimination as the first American-born ref in the NHL.
