From Matt Dennis of the Windsor Star in 1962:
When queried re "curving" a puck, Andy said:
"It's no secret, at times there is a spin on my shots. I picked it up from curling. Talking to curlers in Winnipeg, I was told that a curling rock delivered straight doesn't go true because of the irregularities of the ice. So by twisting the rock, it goes true and is under control.
When I can, I cradle the puck on the heel of the stick, not in the middle as so many other players. I think the puck spins. Others have remarked about it but I do believe it gives me better control once I take aim."
