Based on overall win percentage, Dwane Casey is the most successful Raptors coach in team history. Though it feels strange to say it, a look at the record books will show a team that has steadily improved under his stewardship. There are other factors to consider here of course; the improvement of the existing roster, the collapse of the the Atlantic Division and Eastern Conference, the trades and signings made by General Manager Masai Ujiri. Still, the numbers will always show 48- and 49-win seasons, both franchise-bests, under the watch of Casey.
