I meant offseasons in terms of moves not in season results which have been poor to horrendous.
If these are "mixed results" I'd hate to see what you thought bad results were.
In his 3 seasons here the Leafs have been 29th, 25th, and 29th in goals against, 30th, 28th, and 28th in PK%, and been 29th, 22nd, and 26th overall in those 3 seasons. Over those 3 seasons, the Leafs have 239 points. The only 3 teams worse are Edmonton, Columbus, and the New York Islanders. The Leafs are the 4th worst team in the league in Burke's 3 seasons. That's bad.
