Dave Keon in the late 1950s with the OHA St. Michael's Majors.
"Jim worked really hard, he was always trying to learn," Keon said. "As a trainer with St. Michael's, he learned from (coach) Bob Goldham and Father Bauer. And Jim also learned on his own, when he was at different levels, how to handle people and get the most out of them.
"He got the (GM) job with the Leafs, and I thought he did a really good job. They did some really good drafting. The Montreal Canadiens, mid-1970s and on, it was a difficult task trying to beat them.
"The Leafs didn't get it done, and the owner (Harold Ballard) was a little bit different. Jim was managing with one arm tied behind his back and someone looking over his shoulder. You can't do the things you want to do that way. From that standpoint, Jim was handcuffed, as simple as that."
Indeed, it was while vacationing at his cottage following the 1978-79 season, the Maple Leafs having been eliminated in the Quarterfinals by the Canadiens, that Gregory learned that Ballard had fired him.
The news came when Montreal-based NHL executive vice president Brian O'Neill phoned him to gauge the now-former Toronto GM's interest in a job with the League.
