So much of this season for Kawhi Leonard has been spent on the topic of load management. Well, load management went out the window Sunday night. With his Toronto Raptors’ season on the line, Leonard played a career-high 52 minutes — almost all of them coming after he landed awkwardly on a layup in the first quarter. And he put up his latest stellar line, finishing with 36 points, 9 rebounds and 5 assists to lead Toronto to a 118-112 victory in double overtime against the Milwaukee Bucks in Game 3 of the Eastern Conference finals. The win got the Raptors back into the series, as they now trail 2-1 in this best-of-seven affair — thanks mostly to Leonard’s latest heroics, which came exactly a week after he kept Toronto’s season alive here with his miraculous buzzer-beater to close out the Philadelphia 76ers in Game 7 of the conference semifinals.
