Alie:  ya I read that as well on google, when I looked it up, but I believe I saw one of them either actually do it on television. It may not have counted, because goalies weren't allowed or supposed to score.  I also remember the game against Montreal when  J.C. flattened him. Smith got caught out of his net with the puck, so he ended going up ice and before he realized it he was in the open so kept going, then no one could take the puck away from him so J.C.  (who was a pretty good skater himself) said enough of this nonsense, so he flattened Smith.   After that Smith often took off with the puck, up ice. I think the confusion with Billy Smith's goal is that by his time  in the early 80s a number of goalies where handling the puck, goalies were generally more mobile,  and the league was more receptive to a goalie "potting one", so they credited his as the first.
